SCA: security update for SharpZipLib (GHSA-2x7h-96h5-rq84)

medium Tenable Cloud Security Plugin ID 409160

Description

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

 - SharpZipLib (or #ziplib) is a Zip, GZip, Tar and BZip2 library. Starting version 1.3.0 and prior to
 version 1.3.3, a check was added if the destination file is under destination directory. However, it is
 not enforced that `destDir` ends with slash. If the `destDir` is not slash terminated like
 `/home/user/dir` it is possible to create a file with a name thats begins with the destination directory,
 i.e. `/home/user/dir.sh`. Because of the file name and destination directory constraints, the arbitrary
 file creation impact is limited and depends on the use case. Version 1.3.3 contains a patch for this
 vulnerability. (CVE-2021-32841)
