Debian DSA-2782-1 : polarssl - several vulnerabilities

medium Nessus Plugin ID 70533

Synopsis

The remote Debian host is missing a security-related update.

Description

Multiple security issues have been discovered in PolarSSL, a lightweight crypto and SSL/TLS library :

- CVE-2013-4623 Jack Lloyd discovered a denial of service vulnerability in the parsing of PEM-encoded certificates.

- CVE-2013-5914 Paul Brodeur and TrustInSoft discovered a buffer overflow in the ssl_read_record() function, allowing the potential execution of arbitrary code.

- CVE-2013-5915 Cyril Arnaud and Pierre-Alain Fouque discovered timing attacks against the RSA implementation.

Solution

Upgrade the polarssl packages.

For the oldstable distribution (squeeze), these problems will be fixed in version 1.2.9-1~deb6u1 soon (due to a technical limitation the updates cannot be released synchronously).

For the stable distribution (wheezy), these problems have been fixed in version 1.2.9-1~deb7u1.
