NVD Description

Note: Versions mentioned in the description apply only to the upstream rsync package and not the rsync package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

rsync 3.0.1 before 3.5.0 contains an out-of-bounds write vulnerability in the read_args() function that allows a malicious sender to corrupt adjacent heap memory by sending a crafted argument list. When the argument count causes the argv allocation to be exactly full, the trailing NULL terminator is written one slot beyond the allocation boundary, corrupting adjacent heap memory.
