SCA: security update for SharpZipLib (GHSA-mm6g-mmq6-53ff)
medium Tenable Self-Hosted Container Security Plugin ID 417024
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 1.0.0 and prior to
version 1.3.3, a check was added if the destination file is under a destination directory. However, it is
not enforced that `_baseDirectory` ends with slash. If the _baseDirectory is not slash terminated like
`/home/user/dir` it is possible to create a file with a name thats begins as the destination directory one
level up from the 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
fixed this vulnerability. (CVE-2021-32842)
