Synopsis: Moderate: nss and nspr security, bug fix, and enhancement update
Advisory ID: SLSA-2013:1135-1
Issue Date: 2013-08-05
CVE Numbers: CVE-2013-1620
CVE-2013-0791
—
It was discovered that NSS leaked timing information when decrypting
TLS/SSL and DTLS protocol encrypted records when CBC-mode cipher suites
were used. A remote attacker could possibly use this flaw to retrieve
plain text from the encrypted packets by using a TLS/SSL or DTLS server as
a padding oracle. (CVE-2013-1620)
An out-of-bounds memory read flaw was found in the way NSS decoded certain
certificates. If an application using NSS decoded a malformed certificate,
it could cause the application to crash. (CVE-2013-0791)
This update also fixes the following bugs:
* A defect in the FreeBL library implementation of the Diffie-Hellman (DH)
protocol previously caused Openswan to drop connections.
* A memory leak in the nssutil_ReadSecmodDB() function has been fixed.
In addition, the nss package has been upgraded to upstream version 3.14.3,
and the nspr package has been upgraded to upstream version 4.9.5. These
updates provide a number of bug fixes and enhancements over the previous
versions.
Note that while upstream NSS version 3.14 prevents the use of certificates
that have an MD5 signature, this erratum includes a patch that allows such
certificates by default. To prevent the use of certificates that have an
MD5 signature, set the “NSS_HASH_ALG_SUPPORT” environment variable to
“-MD5”.
After installing this update, applications using NSS or NSPR must be
restarted for this update to take effect.
