Socket
Monthly
Socket versions before 2.041 for Perl have an out-of-bounds heap read. In Socket.xs, pack_ip_mreq_source() checks the length of its source argument before the argument is read, so the check tests the byte length carried over from the preceding multiaddr argument instead. Both addresses occupy a 4-byte field, so a valid multiaddr lets a source of any length pass the check, and the source is then copied into the 4-byte imr_sourceaddr field with a fixed-size copy. A source shorter than 4 bytes is not rejected, and the copy reads up to 3 bytes past the end of its buffer. Calling pack_ip_mreq_source() with a source value shorter than 4 bytes copies adjacent heap memory into the returned packed structure.
Command injection in Cato Networks Socket (versions prior to 25) enables authenticated administrators with web interface access to execute arbitrary commands as root on the underlying system. The vulnerability requires high-level privileges (CVSS PR:H) but offers complete system compromise once accessed, with network-based attack vector and low complexity. No public exploit identified at time of analysis, though the command injection class (CWE-78) is well-understood and straightforward to weaponize once administrative credentials are obtained.
