Summary
squid vulnerabilities
Details
It was discovered that Squid incorrectly handled FTP gateway processing under certain circumstances, which could result in an out-of-bounds read. A remote attacker could use this issue to cause Squid to crash, resulting in a denial of service, or possibly obtain sensitive information. (CVE-2026-47729)
It was discovered that Squid incorrectly handled cache digest processing under certain circumstances, which could result in a heap-based buffer overflow. A remote attacker could use this issue to cause Squid to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2026-50012)
