Subject: [RHSA-2000:046-02] New netscape packages available to fix
JPEG problem
Red Hat, Inc. Security Advisory
Synopsis: New netscape packages available to fix JPEG problem
Advisory ID: RHSA-2000:046-02
Issue date: 2000-07-28
Updated on: 2000-07-28
Product: Red Hat Linux
Keywords: netscpae JPEG
Cross references: N/A
1. Topic:
New netscape packages are available that fix a potential
overflow due to improper input verification in netscape’s JPEG
processing code. It is recommended that users of netscape update to
the fixed packages. Users of Red Hat Linux 6.0 and 6.1 should use
the packages for Red Hat Linux 6.2.
2. Relevant releases/architectures:
Red Hat Linux 5.2 – i386
Red Hat Linux 6.0 – i386
Red Hat Linux 6.1 – i386
Red Hat Linux 6.2 – i386, alpha
3. Problem description:
Netscape’s processing of JPEG comments trusted the length
parameter for comment fields; by manipulating this value, it would
be possible to cause netscape to read in an excessive amount of
data, overwriting memory. Specially designed data could allow a
remote site to execute arbitrary code as the user of netscape.
This vulnerability is fixed in Netscape 4.74.
4. Solution:
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla
for more info):
10165 – Netscape mail client does not compact folders
anymore
13695 – Small glitch in German translation
14506 – Upgrade of netscape-common fails
14657 – /usr/lib/netscape/de_DE: cpio: unlinkfailed
