| Package | Affected versions | Patched versions |
|---|---|---|
| squid | ≥ 3.1, ≤ 3.5.28≥ 4.0, < 4.12≥ 5.0, < 5.0.3 | 4.125.0.3 |
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.
