EulerOS 2.0 SP10 : perl-Encode (EulerOS-SA-2022-2433)

high Nessus Plugin ID 165816

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - Encode.pm, as distributed in Perl through 5.34.0, allows local users to gain privileges via a Trojan horse Encode::ConfigLocal library (in the current working directory) that preempts dynamic module loading.
 Exploitation requires an unusual configuration, and certain 2021 versions of Encode.pm (3.05 through 3.11). This issue occurs because the || operator evaluates @INC in a scalar context, and thus @INC has only an integer value. (CVE-2021-36770)

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 perl-Encode packages.
