CVE-2019-12526 (GCVE-0-2019-12526)

Vulnerability from cvelistv5

Severity ?

CWE

Summary

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.
