GHSA-M34R-4V3R-PP9V

Vulnerability from github – Published: 2026-04-16 09:31 – Updated: 2026-04-22 06:30

Details

In rsync 3.0.1 through 3.4.1, receive_xattr relies on an untrusted length value during a qsort call, leading to a receiver use-after-free. The victim must run rsync with -X (aka --xattrs). On Linux, many (but not all) common configurations are vulnerable. Non-Linux platforms are more widely vulnerable.

Severity ?

7.4 (High)
