GENTOO LINUX SECURITY ANNOUNCEMENT 200301-7
- - --------------------------------------------------------------------

PACKAGE : libpng
SUMMARY : buffer overflow
DATE : 2003-01-08 15:01 UTC
EXPLOIT : remote

- - --------------------------------------------------------------------

- From Debian Security Advisory DSA 213-1:

"Glenn Randers-Pehrson discovered a problem in connection with 16-bit
samples from libpng, an interface for reading and writing PNG
(Portable Network Graphics) format files. The starting offsets for
the loops are calculated incorrectly which causes a buffer overrun
beyond the beginning of the row buffer."

SOLUTION

It is recommended that all Gentoo Linux users who are running
media-libs/libpng-1.2.5-r1 or earlier update their systems as follows:

emerge rsync
emerge libpng

If you also have libpng-1.0.12-r1 or earlier installed update your
system as follows:

emerge \=media-libs/libpng-1.0.12-r2

Finish with:

emerge clean
