RHSA-2013:1829 - Important: nss, nspr, and nss-util security update

Synopsis

Important: nss, nspr, and nss-util security update

Type/Severity

Security Advisory Important

Topic

Updated nss, nspr, and nss-util packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Description

Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. Netscape Portable Runtime (NSPR) provides platform independence for non-GUI operating system facilities.

A flaw was found in the way NSS handled invalid handshake packets. A remote attacker could use this flaw to cause a TLS/SSL client using NSS to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2013-5605)

It was found that the fix for CVE-2013-1620 released via RHSA-2013:1135 introduced a regression causing NSS to read uninitialized data when a decryption failure occurred. A remote attacker could use this flaw to cause a TLS/SSL server using NSS to crash. (CVE-2013-1739)

An integer overflow flaw was discovered in both NSS and NSPR's implementation of certification parsing on 64-bit systems. A remote attacker could use these flaws to cause an application using NSS or NSPR to crash. (CVE-2013-1741, CVE-2013-5607)

It was discovered that NSS did not reject certificates with incompatible key usage constraints when validating them while the verifyLog feature was enabled. An application using the NSS certificate validation API could accept an invalid certificate. (CVE-2013-5606)

Red Hat would like to thank the Mozilla project for reporting CVE-2013-1741, CVE-2013-5606, and CVE-2013-5607. Upstream acknowledges Tavis Ormandy as the original reporter of CVE-2013-1741, Camilo Viecco as the original reporter of CVE-2013-5606, and Pascal Cuoq, Kamil Dudka, and Wan-Teh Chang as the original reporters of CVE-2013-5607.

All NSS, NSPR, and nss-util users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, applications using NSS, NSPR, or nss-util must be restarted for this update to take effect.
