Alpine: multiple perl-gd packages: security update to 2.86-r0

critical Tenable Cloud Security Plugin ID 443104

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - GD versions before 2.86 for Perl allow OS command injection and file overwrite via a 2-arg open() of
 filename arguments in _make_filehandle. GD::Image::_make_filehandle opens a filename argument with Perl's
 2-arg open(), so a filename that begins or ends with a pipe ("| cmd", "cmd |") or begins with a redirect
 ("> path", ">> path") is run as a command or redirect rather than opened as a file. _make_filehandle is
 the single open path behind every filename-accepting constructor (new, newFromPng, newFromJpeg, and the
 rest); the in-memory *Data variants do not open a path and are unaffected. Any caller that forwards
 untrusted input to one of these constructors as a pathname can run an arbitrary command or truncate a file
 under the process UID. (CVE-2026-11526)

Solution

Update the perl-gd library and its related packages to version 2.86-r0 or later.
