Description

An issue was discovered in Squid before 4.9. URN response handling in Squid suffers from a heap-based buffer overflow. When receiving data from a remote server in response to an URN request, Squid fails to ensure that the response can fit within the buffer. This leads to attacker controlled data overflowing in the heap.

Affected configurations

• squid-cache squid (>= 3.0 <= 3.5.28) • squid-cache squid (>= 4.0 <= 4.8) • canonical ubuntu linux 16.04 • canonical ubuntu linux 18.04 • canonical ubuntu linux 19.04 • canonical ubuntu linux 19.10 • fedoraproject fedora 30 • fedoraproject fedora 31 • opensuse leap 15.0 • debian debian linux 8.0 • debian debian linux 9.0 • debian debian linux 10.0
