Debian DSA-3078-1 : libksba - security update

medium Nessus Plugin ID 79600
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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


An integer underflow flaw, leading to a heap-based buffer overflow, was found in the ksba_oid_to_str() function of libksba, an X.509 and CMS (PKCS#7) library. By using special crafted S/MIME messages or ECC based OpenPGP data, it is possible to create a buffer overflow, which could cause an application using libksba to crash (denial of service), or potentially, execute arbitrary code.


Upgrade the libksba packages.

For the stable distribution (wheezy), this problem has been fixed in version 1.2.0-2+deb7u1.

For the upcoming stable distribution (jessie), this problem has been fixed in version 1.3.2-1.
