AlmaLinux 9 : golang-github-cpuguy83-md2man (ALSA-2023:2592)

high Nessus Plugin ID 175634

Synopsis

The remote AlmaLinux host is missing a security update.

Description

The remote AlmaLinux 9 host has a package installed that is affected by a vulnerability as referenced in the ALSA-2023:2592 advisory.

 - Programs which compile regular expressions from untrusted sources may be vulnerable to memory exhaustion or denial of service. The parsed regexp representation is linear in the size of the input, but in some cases the constant factor can be as high as 40,000, making relatively small regexps consume much larger amounts of memory. After fix, each regexp being parsed is limited to a 256 MB memory footprint. Regular expressions whose representation would use more space than that are rejected. Normal use of regular expressions is unaffected. (CVE-2022-41715)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected golang-github-cpuguy83-md2man package.
