Amazon Linux 2 Security Advisory: ALAS-2023-2063
Advisory Release Date: 2023-05-25 17:41 Pacific
Advisory Updated Date: 2023-06-01 23:37 Pacific
Severity:
Important
Issue Overview:
An issue was discovered in Squid before 4.12 and 5.x before 5.0.3. Due to use of a potentially dangerous function, Squid and the default certificate validation helper are vulnerable to a Denial of Service when opening a TLS connection to an attacker-controlled server for HTTPS. This occurs because unrecognized error values are mapped to NULL, but later code expects that each error value is mapped to a valid error string. (CVE-2020-14058)
Affected Packages:
squid
