GLSA-200507-29 : pstotext: Remote execution of arbitrary code
High Nessus Plugin ID 19360
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200507-29 (pstotext: Remote execution of arbitrary code)
Max Vozeler reported that pstotext calls the GhostScript interpreter on untrusted PostScript files without specifying the -dSAFER option.
An attacker could craft a malicious PostScript file and entice a user to run pstotext on it, resulting in the execution of arbitrary commands with the permissions of the user running pstotext.
There is no known workaround at this time.
SolutionAll pstotext users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-text/pstotext-1.8g-r1'
