Vulnerabilities (CVE)

There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed, it can cause an exploitable condition as the process wakes up to terminate and clean all attached files. The system crashes due to the cdev structure being invalid (as already freed) whi ...

A cross-site scripting (XSS) flaw was found in RESTEasy in versions before 3.11.1.Final and before 4.5.3.Final, where it did not properly handle URL encoding when the RESTEASY003870 exception occurs. An attacker could use this flaw to launch a reflected XSS attack.

A flaw was discovered in all versions of Undertow before Undertow 2.2.0.Final, where HTTP request smuggling related to CVE-2017-2666 is possible against HTTP/1.x and HTTP/2 due to permitting invalid characters in an HTTP request. This flaw allows an attacker to poison a web-cache, perform an XSS attack, or obtain sensitive information from request other than their own.

A flaw was found in Keycloak version 8.0.2 and 9.0.0, and was fixed in Keycloak version 9.0.1, where a malicious user registers as oneself. The attacker could then use the remove devices form to post different credential IDs and possibly remove MFA devices for other users.

A flaw was found in Ansible Engine affecting Ansible Engine versions 2.7.x before 2.7.17 and 2.8.x before 2.8.11 and 2.9.x before 2.9.7 as well as Ansible Tower before and including versions 3.4.5 and 3.5.5 and 3.6.3 when using modules which decrypts vault files such as assemble, script, unarchive, win_copy, aws_s3 or copy modules.

A flaw was found in Ansible Engine affecting Ansible Engine versions 2.7.x before 2.7.17 and 2.8.x before 2.8.11 and 2.9.x before 2.9.7 as well as Ansible Tower before and including versions 3.4.5 and 3.5.5 and 3.6.3 when using modules which decrypts vault files such as assemble, script, unarchive, win_copy, aws_s3 or copy modules. The temporary directory is created in /tmp leaves the s ts unencrypted. On Operating Systems which /tmp is not a tmpfs but part of the root partition, the directory is only cleared on boot and the decryp emains when the host is switched off. The system will be vulnerable when the system is not running. So decrypted data must be cleared as soon as possible and the data which normally is encrypted ble.

A flaw was found in Ansible Engine, all versions 2.7.x, 2.8.x and 2.9.x prior to 2.7.17, 2.8.9 and 2.9.6 respectively, when using ansible_facts as a subkey of itself and promoting it to a variable when inject is enabled, overwriting the ansible_facts after the clean. An attacker could take advantage of this by altering the ansible_facts, such as ansible_hosts, users and any other key data which would lead into privilege escalation or code injection.

An issue was discovered in International Components for Unicode (ICU) for C/C++ through 66.1. An integer overflow, leading to a heap-based buffer overflow, exists in the UnicodeString::doAppend() function in common/unistr.cpp.

A remote code execution vulnerability exists in ASP.NET Core software when the software fails to handle objects in memory.An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user, aka 'ASP.NET Core Remote Code Execution Vulnerability'.

A denial of service vulnerability exists when ASP.NET Core improperly handles web requests, aka 'ASP.NET Core Denial of Service Vulnerability'.

Uncontrolled search path in the QT Library before 5.14.0, 5.12.7 and 5.9.10 may allow an authenticated user to potentially enable elevation of privilege via local access.

The JPXStream::init function in Poppler 0.78.0 and earlier doesn't check for negative values of stream length, leading to an Integer Overflow, thereby making it possible to allocate a large memory chunk on the heap, with a size controlled by an attacker, as demonstrated by pdftocairo.

urllib in Python 2.x through 2.7.16 supports the local_file: scheme, which makes it easier for remote attackers to bypass protection mechanisms that blacklist file: URIs, as demonstrated by triggering a urllib.urlopen('local_file:///etc/passwd') call.

PDFDoc::markObject in PDFDoc.cc in Poppler 0.74.0 mishandles dict marking, leading to stack consumption in the function Dict::find() located at Dict.cc, which can (for example) be triggered by passing a crafted pdf file to the pdfunite binary.

When parsing HTTP/1.x header values, Envoy 1.9.0 and before does not reject embedded zero characters (NUL, ASCII 0x0). This allows remote attackers crafting header values containing embedded NUL characters to potentially bypass header matching rules, gaining access to unauthorized resources.

LibreOffice has a feature where documents can specify that pre-installed macros can be executed on various script events such as mouse-over, document-open etc. Access is intended to be restricted to scripts under the share/Scripts/python, user/Scripts/python sub-directories of the LibreOffice install. Protection was added, to address CVE-2019-9852, to avoid a directory traversal attack where scripts in arbitrary locations on the file system could be executed by employing a URL encoding attack to ... LibreOffice has a feature where documents can specify that pre-installed macros can be executed on various script events such as mouse-over, document-open etc. Access is intended to be restricted to scripts under the share/Scripts/python, user/Scripts/python sub-directories of the LibreOffice install. Protection was added, to address CVE-2019-9852, to avoid a directory traversal attack where scripts in arbitrary locations on the file system could be executed by employing a URL encoding attack to defeat the path verification step. However this protection could be bypassed by taking advantage of a flaw in how LibreOffice assembled the final script URL location directly from components of the passed in path as opposed to solely from the sanitized output of the path verification step. This issue affects: Document Foundation LibreOffice 6.2 versions prior to 6.2.7; 6.3 versions prior to 6.3.1.

An integer underflow issue exists in ntfs-3g 2017.3.23. A local attacker could potentially exploit this by running /bin/ntfs-3g with specially crafted arguments from a specially crafted directory to cause a heap buffer overflow, resulting in a crash or the ability to execute arbitrary code. In installations where /bin/ntfs-3g is a setuid-root binary, this could lead to a local escalation of privileges.

An issue was discovered in net/http in Go 1.11.5. CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the second argument to http.NewRequest with \r\n followed by an HTTP header or a Redis command.

An issue was discovered in the iptables firewall module in OpenStack Neutron before 10.0.8, 11.x before 11.0.7, 12.x before 12.0.6, and 13.x before 13.0.3. By setting a destination port in a security group rule along with a protocol that doesn't support that option (for example, VRRP), an authenticated user may block further application of security group rules for instances from any project/tenant on the compute hosts to which it's applied.

The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing.

The Broadcom brcmfmac WiFi driver prior to commit a4176ec356c73a46c07c181c6d04039fafa34a9f is vulnerable to a frame validation bypass. If the brcmfmac driver receives a firmware event frame from a remote source, the is_wlc_event_frame function will cause this frame to be discarded and unprocessed. If the driver receives the firmware event frame from the host, the appropriate handler is called. This frame validation can be bypassed if the bus used is USB (for instance by a wifi dongle).

If the brcmfmac driver receives a firmware event frame from a remote source, the is_wlc_event_frame function will cause this frame to be discarded and unprocessed. If the driver receives the firmware event frame from the host, the appropriate handler is called. This frame validation can be bypassed if the bus used is USB (for instance by a wifi dongle). This can allow firmware event frames from a remote source to be processed. In the worst case scenario, by sending specially-crafted WiFi packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. More typically, this vulnerability will result in denial-of-service conditions.

In the Linux kernel before 4.20.14, expand_downwards in mm/mmap.c lacks a check for the mmap minimum address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task.

In the Linux kernel through 4.20.11, af_alg_release() in crypto/af_alg.c neglects to set a NULL value for a certain structure member, which leads to a use-after-free in sockfs_setattr.
