Debian Security Advisory DSA 107-1                                        Martin Schulze
January 30th, 2002

Package        : jgroff
Vulnerability  : format print
Problem-Type   : local
Debian-specific: no

Basically, this is the same Security Advisory as DSA 072-1, but for
jgroff instead of groff.  The package jgroff contains a version
derived from groff that has japaneze character sets enabled.  This
package is available only in the stable release of Debian, patches for
japanese support have been merged into the main groff package.

The old advisory said:

Zenith Parse found a security problem in groff (the GNU version of
troff).  The pic command was vulnerable to a printf format attack
which made it possible to circumvent the `-S' option and execute
arbitrary code.
