Squid Caching Proxy 55 Vulnerabilities

Two and a half years ago an independent audit was performed on the Squid Caching Proxy, which ultimately resulted in 55 vulnerabilities being discovered in the project's C++ source code. Although some of the issues have been fixed, the majority (35) remain valid. The majority have not been assigned CVEs, and no patches or workarounds are available. Some of the listed issues concern more than one bug, which is why 45 issues are listed, despite there being 55 vulnerabilities in total (10 extra of the result of similar, but different pathways to reproduce a vulnerability). After two and a half years of waiting, the researcher has decided to release the issues publicly.
