EulerOS 2.0 SP5 : squid (EulerOS-SA-2020-2273)

high Nessus Plugin ID 142069

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

- An issue was discovered in Squid before 4.12 and 5.x before 5.0.3. Due to use of a potentially dangerous function, Squid and the default certificate validation helper are vulnerable to a Denial of Service when opening a TLS connection to an attacker-controlled server for HTTPS. This occurs because unrecognized error values are mapped to NULL, but later code expects that each error value is mapped to a valid error string.(CVE-2020-14058)

- An issue was discovered in http/ContentLengthInterpreter.cc in Squid before 4.12 and 5.x before 5.0.3. A Request Smuggling and Poisoning attack can succeed against the HTTP cache. The client sends an HTTP request with a Content-Length header containing '+\ '-' or an uncommon shell whitespace character prefix to the length field-value.(CVE-2020-15049)

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.
