-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ Linux-Mandrake Security Update Advisory ________________________________________________________________________ Package name: netscape Date: July 31st, 2000 Advisory ID: MDKSA-2000:027 Affected versions: 6.0, 6.1, 7.0, 7.1 ________________________________________________________________________ Problem Description: Previous versions of Netscape, from version 3.0 to 4.73 contain a serious overflow flaw due to improper input verification in Netscape''s JPEG processing code. The way Netscape processed JPEG comments trusted the length parameter for comment fields. By manipulating this value, it was possible to cause Netscape to read in an excessive amount of data which would then overwrite memory. Data with a malicious design could allow a remote site to execute arbitrary code as the user of Netscape on the client system. It is highly recommended that everyone using Netscape upgrade to this latest version that fixes the flaw. ________________________________________________________________________ Please verify these md5 checksums of the updates prior to upgrading to ensure the integrity of the downloaded package. You can do this by running the md5sum program on the downloaded package by using "md5sum package.rpm".
