  1. USN-7206-2

    Nicht bewertetKorrektur verfügbar

    rsync regression

    USN-7206-1 fixed vulnerabilities in rsync. The update introduced a regression in rsync. This update fixes the problem. We apologize for the inconvenience. Original advisory details: Simon Scannell, Pedro Gallegos, and Jasiel Spelman discovered that rsync did not properly handle checksum lengths. An attacker could use this issue to execute arbitrary code. (CVE-2024-12084) Simon Scannell, Pedro Gallegos, and Jasiel Spelman discovered that rsync compared checksums with uninitialized memory. An attacker could exploit this issue to leak sensitive information. (CVE-2024-12085) Simon Scannell, Pedro Gallegos, and Jasiel Spelman discove

    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.

    Rsync: race condition in rsync handling symbolic links

    A flaw was found in rsync. This vulnerability arises from a race condition during rsync's handling of symbolic links. Rsync's default behavior when encountering symbolic links is to skip them. If an attacker replaced a regular file with a symbolic link at the right time, it was possible to bypass the default behavior and traverse symbolic links. Depending on the privileges of the rsync process, an attacker could leak sensitive information, potentially leading to privilege escalation.

    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: 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.

    CVE-2022-37434

    zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g., see the nodejs/node reference).

    CVE-2022-29154

    An issue was discovered in rsync before 3.2.5 that allows malicious remote servers to write arbitrary files inside the directories of connecting peers. The server chooses which files/directories are sent to the client. However, the rsync client performs insufficient validation of file names. A malicious rsync server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rsync client target directory and subdirectories (for example, overwrite the .ssh/authorized_keys file).
