CVE-2024-12085

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-2024-12747

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...

CVE-2024-12088

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

CVE-2024-12086

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 wi...

CVE-2024-12084

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 MAXDIGESTLEN exceeds the fixed SUMLENGTH 16 bytes, an attacker can write out of bounds in the sum2 buffer. Mitigation Red Hat...

Heap-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Heap-based Buffer Overflow due to improper handling of attacker-controlled checksum lengths s2length in the code. An anonymous client can leverage this overflow, together with the stack memory exposure described in CVE-2024-12085 to...

Rsync security vulnerabilities

Rsync is a fast and versatile file copying tool open-sourced by RsyncProject. It is used for remote files and local files. A security vulnerability exists in Rsync that stems from a lack of proper symbolic link validation and de-duplication checking, where the server can write files to a location...

CVE-2024-12087: Improper Limitation of a Pathname to a Restricted Directory

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...
