EulerOS 2.0 SP3 : squid (EulerOS-SA-2019-2053)

critical Nessus Plugin ID 129246

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the squid packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - An issue was discovered in Squid 3.3.9 through 3.5.28 and 4.x through 4.7. When Squid is configured to use Digest authentication, it parses the header Proxy-Authorization. It searches for certain tokens such as domain, uri, and qop. Squid checks if this token's value starts with a quote and ends with one. If so, it performs a memcpy of its length minus 2. Squid never checks whether the value is just a single quote (which would satisfy its requirements), leading to a memcpy of its length minus 1.(CVE-2019-12525)

 - The cachemgr.cgi web module of Squid through 4.7 has XSS via the user_name or auth parameter.(CVE-2019-13345)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected squid packages.
