A vulnerability in a2ps' fixps script might allow remote attackers to execute arbitrary code.
|Package||app-text/a2ps on all architectures|
|Affected versions||< 4.14-r5|
|Unaffected versions||>= 4.14-r5|
a2ps is an Any to PostScript filter.
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.
All a2ps users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/a2ps-4.14-r5"
