CVE-2026-27171

CVE-2026-27171 affects zlib versions before 1.3.2. The issue arises from crc32_combine64/crc32_combine_gen64 where a loop in x2nmodp can run with no termination condition, causing an infinite loop and excessive CPU usage (DoS). Multiple connected advisories confirm the DoS impact and the fix in z...
