Vulnerabilities (CVE)

KSmserver in KDE Plasma Workspace (aka plasma-workspace) before 5.27.11.1 and 6.x before 6.0.5.1 allows connections via ICE based purely on the host, i.e., all local connections are accepted. This allows another user on the same machine to gain access to the session manager, e.g., use the session-restore feature to execute arbitrary code as the victim (on the next boot) via earlier use of the /tmp directory.

aRts 1.5.10 and kdelibs3 3.5.10 and earlier do not properly create temporary directories, which allows local users to hijack the IPC by pre-creating the temporary directory.

kpac/script.cpp in KDE kio before 5.32 and kdelibs before 4.14.30 calls the PAC FindProxyForURL function with a full https URL (potentially including Basic Authentication credentials, a query string, or PATH_INFO), which allows remote attackers to obtain sensitive information via a crafted PAC file.

KDE KMail does not encrypt attachments in emails when "automatic encryption" is enabled, which allows remote attackers to obtain sensitive information by sniffing the network.

KDE kmail before 5.5.2 and messagelib before 5.5.2, as distributed in KDE Applications before 17.04.2, do not ensure that a plugin's sign/encrypt action occurs during use of the Send Later feature, which allows remote attackers to obtain sensitive information by sniffing the network.

KDE kdelibs before 4.14.32 and KAuth before 5.34 allow local users to gain root privileges by spoofing a callerID and leveraging a privileged helper app.

ark before 16.12.1 might allow remote attackers to execute arbitrary code via an executable in an archive, related to associated applications.

Multiple cross-site scripting (XSS) vulnerabilities in KDE-Runtime 4.14.3 and earlier, kwebkitpart 1.3.4 and earlier, and kio-extras 5.1.1 and earlier allow remote attackers to inject arbitrary web script or HTML via a crafted URI using the (1) zip, (2) trash, (3) tar, (4) thumbnail, (5) smtps, (6) smtp, (7) smb, (8) remote, (9) recentdocuments, (10) nntps, (11) nntp, (12) network, (13) mbox, (14) ldaps, (15) ldap, (16) fonts, (17) file, (18) desktop, (19) cgi, (20) bookmarks, or (21) ar scheme, ... Multiple cross-site scripting (XSS) vulnerabilities in KDE-Runtime 4.14.3 and earlier, kwebkitpart 1.3.4 and earlier, and kio-extras 5.1.1 and earlier allow remote attackers to inject arbitrary web script or HTML via a crafted URI using the (1) zip, (2) trash, (3) tar, (4) thumbnail, (5) smtps, (6) smtp, (7) smb, (8) remote, (9) recentdocuments, (10) nntps, (11) nntp, (12) network, (13) mbox, (14) ldaps, (15) ldap, (16) fonts, (17) file, (18) desktop, (19) cgi, (20) bookmarks, or (21) ar scheme, which is not properly handled in an error message.

kde-workspace 4.2.0 and plasma-workspace before 5.1.95 allows remote attackers to obtain input events, and consequently obtain passwords, by leveraging access to the X server when the screen is locked.

kio/usernotificationhandler.cpp in the POP3 kioslave in kdelibs 4.10.95 before 4.13.3 does not properly generate warning notifications, which allows man-in-the-middle attackers to obtain sensitive information via an invalid certificate.

KDE kdelibs before 4.14 and kauth before 5.1 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, related to CVE-2013-4288 and "PID reuse race conditions."

kinit in KDE Frameworks before 5.23.0 uses weak permissions (644) for /tmp/xauth-xxx-_y, which allows local users to obtain X11 cookies of other users and consequently capture keystrokes and possibly gain privileges by reading the file.

Turning all screens off in Plasma-workspace and kscreenlocker while the lock screen is shown can result in the screen being unlocked when turning a screen on again.

KMail since version 5.3.0 used a QWebEngine based viewer that had JavaScript enabled. HTML Mail contents were not sanitized for JavaScript and included code was executed.

A maliciously crafted command line for kdesu can result in the user only seeing part of the commands that will actually get executed as super user.

Through a malicious URL that contained a quote character it was possible to inject HTML code in KMail's plaintext viewer. Due to the parser used on the URL it was not possible to include the equal sign (=) or a space into the injected HTML, which greatly reduces the available HTML functionality. Although it is possible to include an HTML comment indicator to hide content.

The KDE Clock KCM policykit helper in kde-workspace before 4.11.14 and plasma-desktop before 5.1.1 allows local users to gain privileges via a crafted ntpUtility (ntp utility name) argument.

kwalletd in KWallet before KDE Applications 14.12.0 uses Blowfish with ECB mode instead of CBC mode when encrypting the password store, which makes it easier for attackers to guess passwords via a codebook attack.

plasma-workspace before 5.1.95 allows remote attackers to obtain passwords via a Trojan horse Look and Feel package.

Directory traversal vulnerability in KArchive before 5.24, as used in KDE Frameworks, allows remote attackers to write to arbitrary files via a ../ (dot dot slash) in a filename in an archive file, related to KNewsstuff downloads.

KMail since version 5.3.0 used a QWebEngine based viewer that had JavaScript enabled. Since the generated html is executed in the local file security context by default access to remote and local URLs was enabled.

Directory traversal vulnerability in Ark 4.7.x and earlier allows remote attackers to delete and force the display of arbitrary files via .. (dot dot) sequences in a zip file.

Race condition in workspace/krunner/lock/lockdlg.cc in the KRunner lock module in kdebase in KDE SC 4.4.0 allows physically proximate attackers to bypass KScreenSaver screen locking and access an unattended workstation by pressing the Enter key at a certain time, related to multiple forked processes.

The HTMLQuoteColorer::process function in messageviewer/htmlquotecolorer.cpp in KDE PIM 4.6 through 4.8 does not disable JavaScript, Java, and Plugins, which allows remote attackers to inject arbitrary web script or HTML via a crafted email.

KDE-Workspace 4.10.5 and earlier does not properly handle the return value of the glibc 2.17 crypt and pw_encrypt functions, which allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via (1) an invalid salt or a (2) DES or (3) MD5 encrypted password, when FIPS-140 is enable, to KDM or an (4) invalid password to KCheckPass.

Directory traversal vulnerability in the KGetMetalink::File::isValidNameAttr function in ui/metalinkcreator/metalinker.cpp in KGet in KDE SC 4.6.2 and earlier allows remote attackers to create arbitrary files via a .. (dot dot) in the name attribute of a file element in a metalink file. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-1000.

Use-after-free vulnerability in khtml/rendering/render_replaced.cpp in Konqueror in KDE 4.7.3, when the context menu is shown, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by accessing an iframe when it is being updated.

Cross-site scripting (XSS) vulnerability in the KHTMLPart::htmlError function in khtml/khtml_part.cpp in Konqueror in KDE SC 4.4.0 through 4.6.1 allows remote attackers to inject arbitrary web script or HTML via the URI in a URL corresponding to an unavailable web site.

rendering/render_replaced.cpp in Konqueror in KDE before 4.9.3 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted web page, related to "trying to reuse a frame with a null part."

The KDE SSL Wrapper (KSSL) API in KDE SC 4.6.0 through 4.7.1, and possibly earlier versions, does not use a certain font when rendering certificate fields in a security dialog, which allows remote attackers to spoof the common name (CN) of a certificate via rich text.

Heap-based buffer overflow in the RLE decompression functionality in the TranscribePalmImageToJPEG function in generators/plucker/inplug/image.cpp in Okular in KDE SC 4.3.0 through 4.5.0 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted image in a PDB file.

KGet 2.4.2 in KDE SC 4.0.0 through 4.4.3 does not properly request download confirmation from the user, which makes it easier for remote attackers to overwrite arbitrary files via a crafted metalink file.

kioslave/http/http.cpp in KIO in kdelibs 4.10.3 and earlier allows attackers to discover credentials via a crafted request that triggers an "internal server error," which includes the username and password in an error message.

The FoFiType1::parse function in fofi/FoFiType1.cc in the PDF parser in xpdf before 3.02pl5, poppler 0.8.7 and possibly other versions up to 0.15.1, kdegraphics, and possibly other products allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a PDF file with a crafted PostScript Type1 font that contains a negative array index, which bypasses input validation and triggers memory corruption.

kcheckpass passes a user-supplied argument to the pam_start function, often within a setuid environment, which allows local users to invoke any configured PAM stack, and possibly trigger unintended side effects, via an arbitrary valid PAM service name, a different vulnerability than CVE-2011-4122. NOTE: the vendor indicates that the possibility of resultant privilege escalation may be "a bit far-fetched."

Heap-based buffer overflow in the read function in filters/words/msword-odf/wv2/src/styles.cpp in the Microsoft import filter in KOffice 2.3.3 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted ODF style in an ODF document. NOTE: this is the same vulnerability as CVE-2012-3456, but it was SPLIT by the CNA even though Calligra and KOffice share the same codebase.

khtml/imload/scaledimageplane.h in Konqueror in KDE 4.7.3 allows remote attackers to cause a denial of service (crash) and possibly read memory via large canvas dimensions, which leads to an unexpected sign extension and a heap-based buffer over-read.

Directory traversal vulnerability in KGet in KDE SC 4.0.0 through 4.4.3 allows remote attackers to create arbitrary files via directory traversal sequences in the name attribute of a file element in a metalink file.

Cross-site scripting (XSS) vulnerability in webkitpart.cpp in kwebkitpart allows remote attackers to inject arbitrary web script or HTML via a URL associated with a nonexistent domain name, related to a "universal XSS" issue, a similar vulnerability to CVE-2010-2536.

Race condition in backend/ctrl.c in KDM in KDE Software Compilation (SC) 2.2.0 through 4.4.2 allows local users to change the permissions of arbitrary files, and consequently gain privileges, by blocking the removal of a certain directory that contains a control socket, related to improper interaction with ksm.
