Debian DSA-3413-1 : openssl - security update

Medium Nessus Plugin ID 87212

Synopsis

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

Description

Multiple vulnerabilities have been discovered in OpenSSL, a Secure Sockets Layer toolkit. The Common Vulnerabilities and Exposures project identifies the following issues :

- CVE-2015-3194 Loic Jonas Etienne of Qnective AG discovered that the signature verification routines will crash with a NULL pointer dereference if presented with an ASN.1 signature using the RSA PSS algorithm and absent mask generation function parameter. A remote attacker can exploit this flaw to crash any certificate verification operation and mount a denial of service attack.

- CVE-2015-3195 Adam Langley of Google/BoringSSL discovered that OpenSSL will leak memory when presented with a malformed X509_ATTRIBUTE structure.

- CVE-2015-3196 A race condition flaw in the handling of PSK identify hints was discovered, potentially leading to a double free of the identify hint data.

Solution

Upgrade the openssl packages.

For the oldstable distribution (wheezy), these problems have been fixed in version 1.0.1e-2+deb7u18.

For the stable distribution (jessie), these problems have been fixed in version 1.0.1k-3+deb8u2.
