[GLSA-200410-18] Ghostscript: Insecure temporary file use in multiple scripts Vulnerability Scan
Vulnerability Scan Summary
Ghostscript: Insecure temporary file use in multiple scripts
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200410-18
(Ghostscript: Insecure temporary file use in multiple scripts)
The pj-gs.sh, ps2epsi, pv.sh and sysvlp.sh scripts create temporary files
in world-writeable directories with predictable names.
Impact
A local attacker could create symbolic links in the temporary files
directory, pointing to a valid file somewhere on the filesystem. When an
affected script is called, this would result in the file to be overwritten
with the rights of the user running the script, which could be the root
user.
Workaround
There is no known workaround at this time.
