USN-218-1: netpbm vulnerabilities

netpbm vulnerabilities
Releases
Details
Two buffer overflows were discovered in the 'pnmtopng' tool, which
were triggered by processing an image with exactly 256 colors when
using the -alpha option (CVE-2005-3662) or by processing a text file
with very long lines when using the -text option (CVE-2005-3632).
A remote attacker could exploit these to execute arbitrary code by
tricking an user or an automated system into processing a specially
crafted PNM file with pnmtopng.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 5.10
-
netpbm
-
Ubuntu 5.04
-
netpbm
-
Ubuntu 4.10
-
netpbm
-
In general, a standard system update will make all the necessary changes.
