Affected Packages 18

CVEs 4

Several security issues were fixed in Squid.

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)
