GLSA-201701-67 : a2ps: Arbitrary code execution
Medium Nessus Plugin ID 96853
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201701-67 (a2ps: Arbitrary code execution)
a2ps’ fixps script does not invoke gs with the -dSAFER option.
Remote attackers, by enticing a user to process a specially crafted PostScript file, could delete arbitrary files or execute arbitrary code with the privileges of the process.
There is no known workaround at this time.
SolutionAll a2ps users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-text/a2ps-4.14-r5'
