Summary

squid, squid3 vulnerabilities

Details

Jeriko One discovered that Squid incorrectly handled memory when connected to an FTP server. A remote attacker could possibly use this issue to obtain sensitive information from Squid memory. (CVE-2019-12528)

Regis Leroy discovered that Squid incorrectly handled certain HTTP requests. A remote attacker could possibly use this issue to access server resources prohibited by earlier security filters. (CVE-2020-8449)

Guido Vranken discovered that Squid incorrectly handled certain buffer operations when acting as a reverse proxy. A remote attacker could use this issue to cause Squid to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2020-8450)

Aaron Costello discovered that Squid incorrectly handled certain NTLM authentication credentials. A remote attacker could possibly use this issue to cause Squid to crash, resulting in a denial of service. (CVE-2020-8517)
