From 1.0.0 until 4.14.6 and 5.0.0-beta2, HandleSecureMessage() in src/remoted/secure.c passes a pointer inside its stack buffer to ReadSecMSG(), and src/os_crypto/shared/msgs.c decompresses up to OS_MAXSTR bytes at that offset. For an encrypted agent message on TCP port 1514 that expands to 65,536 bytes, os_zlib_uncompress() writes a terminating null byte beyond the end of the destination buffer. The resulting stack out-of-bounds write in the root-level remoted daemon can crash message processing and disrupt agent communications. This issue is fixed in versions 4.14.6 and 5.0.0-beta2."}], "lastModified": "2026-09-09T21:19:49.197", "sourceIdentifier": "security-advisories@github.com"}
