Synopsis ========
Two buffer overflows in enscript might lead to the execution of arbitrary code.
Background ==========
enscript is a powerful ASCII to PostScript file converter.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/enscript < 1.6.4-r4 >= 1.6.4-r4
Description ===========
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).
Impact ======
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All enscript users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/enscript-1.6.4-r4"
