Title
=====

Two Debian Security Advisories:

1. Debian Security Advisory DSA 574-1 -  New cabextract packages fix unintended directory traversal.

2. Debian Security Advisory DSA 575-1 -  New catdoc packages fix temporary file vulnerability.



Detail
====== 

1. The upstream developers discovered a problem in cabextract, a tool to extract cabinet files.  
The program was able to overwrite files in upper directories.  This could lead an attacker to 
overwrite arbitrary files.


2. A temporary file problem has been discovered in xlsview from the catdoc suite, convertors 
from Word to TeX and plain text, which could lead to local users being able to overwrite 
arbitrary files via a symlink attack on predictable temporary file names.

Vulnerability  : missing directory sanitising
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2004-0916
Debian Bug     : 277522

The upstream developers discovered a problem in cabextract, a tool to extract cabinet files.  
The program was able to overwrite files in upper directories.  This could lead an attacker
to overwrite arbitrary files.

For the stable distribution (woody) this problem has been fixed in version 0.2-2b.

For the unstable distribution (sid) this problem has been fixed in version 1.1-1.

We recommend that you upgrade your cabextract package.

CVE ID         : CAN-2003-0193
Debian Bug     : 183525

A temporary file problem has been discovered in xlsview from the catdoc suite, convertors from Word 
to TeX and plain text, which could lead to local users being able to overwrite arbitrary files via a 
symlink attack on predictable temporary file names.

For the stable distribution (woody) this problem has been fixed in version 0.91.5-1.woody3.

For the unstable distribution (sid) this problem has been fixed in version 0.91.5-2.
