Description Tomas Hoger 2008-10-13 11:09:25 EDT
Ulf Harnhammar of the Secunia Research discovered a buffer overflow in enscript:

The vulnerability is caused due to a boundary error within the
"read_special_escape()" function in src/psgen.c. This can be exploited
to cause a stack-based buffer overflow by tricking the user into
converting a malicious file.

Successful exploitation allows execution of arbitrary code, but requires
that special escapes processing is enabled with the "-e" option.

The vulnerability is confirmed in versions 1.6.1 and 1.6.4 (beta). Other
versions may also be affected.
