Vulnerabilities (CVE)

A path traversal vulnerability exists in rsync. It stems from behavior enabled by the `--inc-recursive` option, a default-enabled option for many client options and can be enabled by the server even if not explicitly enabled by the client. When using the `--inc-recursive` option, a lack of proper symlink verification coupled with deduplication checks occurring on a per-file-list basis could allow a server to write files outside of the client's intended destination directory.

It stems from behavior enabled by the `--inc-recursive` option, a default-enabled option for many client options and can be enabled by the server even if not explicitly enabled by the client. When using the `--inc-recursive` option, a lack of proper symlink verification coupled with deduplication checks occurring on a per-file-list basis could allow a server to write files outside of the client's intended destination directory. A malicious server could write malicious files to arbitrary locations named after valid directories/paths on the client.

A flaw was found in rsync which could be triggered when rsync compares file checksums. This flaw allows an attacker to manipulate the checksum length (s2length) to cause a comparison between a checksum and uninitialized memory and leak one byte of uninitialized stack data at a time.

A flaw was found in rsync. When using the `--safe-links` option, the rsync client fails to properly verify if a symbolic link destination sent from the server contains another symbolic link within it. This results in a path traversal vulnerability, which may lead to arbitrary file write outside the desired directory.

A flaw was found in rsync. It could allow a server to enumerate the contents of an arbitrary file from the client's machine. This issue occurs when files are being copied from a client to a server. During this process, the rsync server will send checksums of local data to the client to compare with in order to determine what data needs to be sent to the server. By sending specially constructed checksum values for arbitrary files, an attacker may be able to reconstruct the data of those files byt ... A flaw was found in rsync.

The gencert.sh script, when installing OpenLDAP before 2.1.30-r10, 2.2.x before 2.2.28-r7, and 2.3.x before 2.3.30-r2 as an ebuild in Gentoo Linux, does not create temporary directories in /tmp securely during emerge, which allows local users to overwrite arbitrary files via a symlink attack.

expn in the am-utils and net-fs packages for Gentoo, rPath Linux, and other distributions, allows local users to overwrite arbitrary files via a symlink attack on the expn[PID] temporary file. NOTE: this is the same issue as CVE-2003-0308.1.

Interpretation conflict in PHP Toolkit before 1.0.1 on Gentoo Linux might allow local users to cause a denial of service (PHP outage) and read contents of PHP scripts by creating a file with a one-letter lowercase alphabetic name, which triggers interpretation of a certain unquoted [a-z] argument as a matching shell glob for this name, rather than interpretation as the literal [a-z] regular-expression string, and consequently blocks the launch of the PHP interpreter within the Apache HTTP Server ...

Vixie Cron before 4.1-r10 on Gentoo Linux is installed with insecure permissions, which allows local users to cause a denial of service (cron failure) by creating hard links, which results in a failed st_nlink check in database.c.

The docert function in ssl-cert.eclass, when used by src_compile or src_install on Gentoo Linux, stores the SSL key in a binpkg, which allows local users to extract the key from the binpkg, and causes multiple systems that use this binpkg to have the same SSL key and certificate.

Cross-site scripting (XSS) vulnerability in the wp_explain_nonce function in the nonce AYS functionality (wp-includes/functions.php) for WordPress 2.0 before 2.0.9 and 2.1 before 2.1.1 allows remote attackers to inject arbitrary web script or HTML via the file parameter to wp-admin/templates.php, and possibly other vectors involving the action variable.

ViewVC before 1.0.5 provides revision metadata without properly checking whether access was intended, which allows remote attackers to obtain sensitive information by reading (1) forbidden pathnames in the revision view, (2) log history that can only be reached by traversing a forbidden object, or (3) forbidden diff view path parameters.

ViewVC before 1.0.5 includes "all-forbidden" files within search results that list CVS or Subversion (SVN) commits, which allows remote attackers to obtain sensitive information.

etc-update in Portage before 2.1.3.11 on Gentoo Linux relies on the umask to set permissions for the merge file, often resulting in permissions weaker than those of the original files, which might allow local users to obtain sensitive information by reading the merge file.

Off-by-one error in the QUtf8Decoder::toUnicode function in Trolltech Qt 3 allows context-dependent attackers to cause a denial of service (crash) via a crafted Unicode string that triggers a heap-based buffer overflow. NOTE: Qt 4 has the same error in the QUtf8Codec::convertToUnicode function, but it is not exploitable.

The Linux Security Auditing Tool (LSAT) allows local users to overwrite arbitrary files via a symlink attack on temporary files, as demonstrated using /tmp/lsat1.lsat.

Eval injection vulnerability in (1) courier-imapd.indirect and (2) courier-pop3d.indirect in Courier-IMAP before 4.0.6-r2, and 4.1.x before 4.1.2-r1, on Gentoo Linux allows remote attackers to execute arbitrary commands via the XMAILDIR variable, related to the LOGINRUN variable.
