All supported architectures
enscript suffers from vulnerabilities and design flaws, potentially
resulting in the execution of arbitrary code.
enscript is a powerful ASCII to PostScript file converter.
Erik Sjolund discovered several issues in enscript: it suffers
from several buffer overflows (CAN-2004-1186), quotes and shell escape
characters are insufficiently sanitized in filenames (CAN-2004-1185),
and it supported taking input from an arbitrary command pipe, with
unwanted side effects (CAN-2004-1184).
An attacker could design malicious files or input data which, once
feeded into enscript, would trigger the execution of arbitrary code
with the rights of the user running enscript.
There is no known workaround at this time.
All enscript users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/enscript-1.6.3-r3"
