[GLSA-200410-18] Ghostscript: Insecure temporary file use in multiple scripts |
||
Ghostscript: Insecure temporary file use in multiple scripts Detailed Explanation for this Vulnerability Assessment 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.
