CVE-2026-63209 (GCVE-0-2026-63209)

Vulnerability from cvelistv5 – Published: 2026-09-29 14:58 – Updated: 2026-09-29 16:32

Title

Integer Overflow or Wraparound and Out-of-bounds Write in compress

Summary

compress provides various compression algorithms. Prior to version 1.18.7, a signed integer overflow vulnerability in s2.NewDict() allows an attacker to bypass repeat index validation by supplying a dictionary with a uvarint-encoded repeat value exceeding MaxInt64. When Dict.Encode() is subsequently called, the overflowed negative repeat value causes an out-of-bounds memory access via unsafe.Pointer arithmetic, crashing the process with SIGSEGV. This issue has been patched in version 1.18.7.

Severity
