EulerOS 2.0 SP2 : libmspack (EulerOS-SA-2021-2398)

medium Nessus Plugin ID 153358

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the libmspack package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

- chmextract.c in the chmextract sample program, as distributed with libmspack before 0.8alpha, does not protect against absolute/relative pathnames in CHM files, leading to Directory Traversal. NOTE: the vendor disputes that this is a libmspack vulnerability, because chmextract.c was only intended as a source-code example, not a supported application.(CVE-2018-18586)

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 libmspack package.
