EulerOS 2.0 SP8 : patch (EulerOS-SA-2020-1022)

high Nessus Plugin ID 132615

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

 - do_ed_script in pch.c in GNU patch through 2.7.6 does not block strings beginning with a ! character. NOTE:
 this is the same commit as for CVE-2019-13638, but the ! syntax is specific to ed, and is unrelated to a shell metacharacter.(CVE-2018-20969)

 - GNU patch through 2.7.6 is vulnerable to OS shell command injection that can be exploited by opening a crafted patch file that contains an ed style diff payload with shell metacharacters. The ed editor does not need to be present on the vulnerable system. This is different from CVE-2018-1000156.(CVE-2019-13638)

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 patch packages.
