Updated nss and nspr packages that fix three security issues are now
available for Red Hat Enterprise Linux 5.
Red Hat Product Security has rated this update as having Critical 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.
Network Security Services (NSS) is a set of libraries designed to support
cross-platform development of security-enabled client and server
applications. Netscape Portable Runtime (NSPR) provides platform
independence for non-GUI operating system facilities.
A use-after-poison flaw and a heap-based buffer overflow flaw were found in
the way NSS parsed certain ASN.1 structures. An attacker could use these
flaws to cause NSS to crash or execute arbitrary code with the permissions
of the user running an application compiled against the NSS library.
A heap-based buffer overflow was found in NSPR. An attacker could use this
flaw to cause NSPR to crash or execute arbitrary code with the permissions
of the user running an application compiled against the NSPR library.
Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Tyson Smith, David Keeler and Ryan Sleevi as the
