GLSA-200812-02 : enscript: User-assisted execution of arbitrary code
High Nessus Plugin ID 35019
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200812-02 (enscript: User-assisted execution of arbitrary code)
Two stack-based buffer overflows in the read_special_escape() function in src/psgen.c have been reported. Ulf Harnhammar of Secunia Research discovered a vulnerability related to the 'setfilename' command (CVE-2008-3863), and Kees Cook of Ubuntu discovered a vulnerability related to the 'font' escape sequence (CVE-2008-4306).
An attacker could entice a user or automated system to process specially crafted input with the special escapes processing enabled using the '-e' option, possibly resulting in the execution of arbitrary code.
There is no known workaround at this time.
SolutionAll enscript users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-text/enscript-1.6.4-r4'
