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
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
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.
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
6. RPMs required:
Red Hat Linux 5.2:
Red Hat Linux 6.2:
