Several vulnerabilities were discovered in rsync, a fast, versatile,
remote (and local) file-copying tool.
CVE-2024-12084
Simon Scannell, Pedro Gallegos and Jasiel Spelman discovered a
heap-based buffer overflow vulnerability due to improper handling of
attacker-controlled checksum lengths. A remote attacker can take
advantage of this flaw for code execution.
CVE-2024-12085
Simon Scannell, Pedro Gallegos and Jasiel Spelman reported a flaw in
the way rsync compares file checksums, allowing a remote attacker to
trigger an information leak.
CVE-2024-12086
Simon Scannell, Pedro Gallegos and Jasiel Spelman discovered a flaw
which would result in a server leaking contents of an arbitrary file
from the client’s machine.
CVE-2024-12087
Simon Scannell, Pedro Gallegos and Jasiel Spelman reported a path
traversal vulnerability in the rsync daemon affecting the
–inc-recursive option, which could allow a server to write files
outside of the client’s intended destination directory.
CVE-2024-12088
Simon Scannell, Pedro Gallegos and Jasiel Spelman reported that when
using the –safe-links option, rsync fails to properly verify if a
symbolic link destination contains another symbolic link with it,
resulting in path traversal and arbitrary file write outside of the
desired directory.
CVE-2024-12747
Aleksei Gorban “loqpa” discovered a race condition when handling
symbolic links resulting in an information leak which may enable
escalation of privileges.
