Medium Nessus Plugin ID 20449
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionGreg Roelofs discovered and fixed several buffer overflows in pnmtopng which is also included in netpbm, a collection of graphic conversion utilities, that can lead to the execution of arbitrary code via a specially crafted PNM file.
Multiple buffer overflows in pnmtopng in netpbm 10.0 and earlier allow attackers to execute arbitrary code via a crafted PNM file.
An off-by-one buffer overflow in pnmtopng, when using the -alpha command line option, allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted PNM file with exactly 256 colors. (CVE-2005-3662)
The updated packages have been patched to correct this problem.
