CVE-2026-50012 - Squid: Memory corruption in cache_digest reply handling
CVE ID :CVE-2026-50012
Published : July 16, 2026, 4:11 p.m. | 36 minutes ago
Description :Squid is a caching proxy for the Web. Prior to 7.6, due to an improper input validation bug in cache digest reply handling (peerDigestSwapInMask in src/peer_digest.cc), Squid is vulnerable to a heap-based buffer overflow: a cache digest's on-the-wire size may be larger than the mask_size declared within the digest, so a trusted peer sending a maliciously crafted reply to a cache_digest request message can trigger the overflow. This attack is limited to Squid instances compiled with the --enable-cache-digests option and configured with cache_peer entries. This issue is fixed in version 7.6.
Severity: 0.0 | NA
