Package        : pstotext
Vulnerability  : missing input sanitising
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2005-2536
BugTraq ID     : 14378
Debian Bug     : 319758

Max Vozeler discovered that pstotext, a utility to extract text from
PostScript and PDF files, did not execute ghostscript with the -dSAFER
argument, which prevents potential malicious operations to happen.

For the old stable distribution (woody) this problem has been fixed in
version 1.8g-5woody1.

For the stable distribution (sarge) this problem has been fixed in
version 1.9-1sarge1.

For the unstable distribution (sid) this problem has been fixed in
version 1.9-2.

We recommend that you upgrade your pstotext package.
