SCA: security update for sharpcompress (GHSA-jp7f-grcv-6mjf)

medium Tenable Self-Hosted Container Security Plugin ID 416486

Description

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

 - SharpCompress is a fully managed C# library to deal with many compression types and formats. Versions
 prior to 0.29.0 are vulnerable to partial path traversal. SharpCompress recreates a hierarchy of
 directories under destinationDirectory if ExtractFullPath is set to true in options. In order to prevent
 extraction outside the destination directory the destinationFileName path is verified to begin with
 fullDestinationDirectoryPath. However, prior to version 0.29.0, it is not enforced that
 fullDestinationDirectoryPath ends with slash. If the destinationDirectory 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. This issue is fixed
 in SharpCompress version 0.29.0. (CVE-2021-39208)
