Rsync: --safe-links option bypass leads to path traversal

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.

Rsync: rsync server leaks arbitrary client files

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 byte-by-byte based on the responses from the client.

Rsync: heap buffer overflow in rsync due to improper checksum length handling

A heap-based buffer overflow flaw was found in the rsync daemon. This issue is due to improper handling of attacker-controlled checksum lengths (s2length) in the code. When MAX_DIGEST_LEN exceeds the fixed SUM_LENGTH (16 bytes), an attacker can write out of bounds in the sum2 buffer.

Rsync: info leak via uninitialized stack contents

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.

Rsync: path traversal vulnerability in rsync

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. A malicious server could write malicious files to arbitrary locations named after valid directories/paths on the client.

ssh: Prefix truncation attack on Binary Packet Protocol (BPP)

The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

ViewVC before 1.0.5 stores sensitive information under the web root with insufficient access control, which allows remote attackers to read files and list folders under the hidden CVSROOT folder.

Xdg-utils 1.0.2 and earlier allows user-assisted remote attackers to execute arbitrary commands via shell metacharacters in a URL argument to (1) xdg-open or (2) xdg-email.

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.

NVIDIA drivers (nvidia-drivers) before 1.0.7185, 1.0.9639, and 100.14.11, as used in Gentoo Linux and possibly other distributions, creates /dev/nvidia* device files with insecure permissions, which allows local users to modify video card settings, cause a denial of service (crash or physical video card damage), and 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.

clamav: undocumented bzlib issue

Unspecified vulnerability in the bzip2 decompression algorithm in nsis/bzlib_private.h in ClamAV before 0.92 has unknown impact and remote attack vectors.

am-utils: insecure usage of temporary files

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.

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.

The set_default_speeds function in backend/backend.c in NVidia NVClock before 0.8b2 allows local users to overwrite arbitrary files via a symlink attack on the /tmp/nvclock temporary file.

QT off by one buffer overflow

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 gnu regular expression code in file 4.20 allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted document with a large number of line feed characters, which is not well handled by OS/2 REXX regular expressions that use wildcards, as originally reported for AMaViS.

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.

Glibc integer overflow

Integer overflow in the process_envvars function in elf/rtld.c in glibc before 2.5-rc4 might allow local users to execute arbitrary code via a large LD_HWCAP_MASK environment variable value. NOTE: the glibc maintainers state that they do not believe that this issue is exploitable for code execution

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.
