Security Advisory Updated libpng packages fix buffer overflow

Advisory: RHSA-2003:006-10
Type: Security Advisory
Severity: N/A
Issued on: 2003-01-15
Last updated on: 2003-01-15
Affected Products: Red Hat Linux 6.2

CVEs (cve.mitre.org): CVE-2002-1363

Details

Updated libpng packages are available that fix a buffer overflow vulnerability.

[Updated 15 Jan 2003]
Advisory updated to include libpng10 packages for Red Hat Linux 8.0.
libpng10 contains compatibility libraries used to run binaries that were
linked dynamically with libpng 1.0.x.

The libpng package contains a library of functions for creating and
manipulating PNG (Portable Network Graphics) image format files. PNG
is a bit-mapped graphics format similar to the GIF format.

Unpatched versions of libpng 1.2.1 and earlier do not correctly calculate
offsets, which leads to a buffer overflow and the possibility of arbitrary
code execution. This could be exploited by an attacker creating a
carefully crafted PNG file which could execute arbitrary code when the
victim views it.

Packages within Red Hat Linux, such as Mozilla, make use of the shared
libpng library. Therefore, all users are advised to upgrade to the errata
packages. For Red Hat Linux 8.0 the packages contain libpng 1.2.2 which is
not vulnerable to this issue. For Red Hat Linux 6.2, 7, 7.1, 7.2 and 7.3
the packages contain libpng 1.0.14 with a backported patch that corrects
this issue.


Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
