Name of the Vulnerable Software and Affected Versions pxz version 4.999.99 Beta 3

Description A race condition exists due to weak file permissions for the output file when compressing a file. This allows local users to bypass the intended access restrictions before the permission is changed to match the original file.

Recommendations For pxz version 4.999.99 Beta 3, consider changing the file permissions manually after compression to match the original file's permissions until a patch is available. As a temporary workaround, restrict access to the output file to minimize the risk of exploitation.
