Risk 4 : Red Hat Local Checks

Updated Mozilla packages that fix vulnerabilities in S/MIME parsing as well as other issues and bugs are now available.

Mozilla is a Web browser and mail reader, designed for standards compliance, performance and portability. Network Security Services (NSS) is a set of libraries designed to support cross-platform development of security-enabled server applications.

NISCC testing of implementations of the S/MIME protocol uncovered a number of bugs in NSS versions prior to 3.9. The parsing of unexpected ASN.1 constructs within S/MIME data could cause Mozilla to crash or consume large amounts of memory. A remote attacker could potentially trigger these bugs by sending a carefully-crafted S/MIME message to a victim. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0564 to this issue.

Andreas Sandblad discovered a cross-site scripting issue that affects various versions of Mozilla. When linking to a new page it is still possible to interact with the old page before the new page has been successfully loaded. Any Javascript events will be invoked in the context of the new page, making cross-site scripting possible if the different pages belong to different domains. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0191 to this issue.

Flaws have been found in the cookie path handling between a number of Web browsers and servers. The HTTP cookie standard allows a Web server supplying a cookie to a client to specify a subset of URLs on the origin server to which the cookie applies. Web servers such as Apache do not filter returned cookies and assume that the client will only send back cookies for requests that fall within the server-supplied subset of URLs. However, by supplying URLs that use path traversal (/../) and character encoding, it is possible to fool many browsers into sending a cookie to a path outside of the originally-specified subset. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0594 to this issue.

Users of Mozilla are advised to upgrade to these updated packages, which contain Mozilla version 1.4.2 and are not vulnerable to these issues.
