Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS

Summary:

Libtasn1 could be made to crash or run programs if it processed specially crafted data.

Software Description: - libtasn1-6: Library to manage ASN.1 structures - libtasn1-3: Library to manage ASN.1 structures

Details:

Hanno Böck discovered that Libtasn1 incorrectly handled certain ASN.1 data. A remote attacker could possibly exploit this with specially crafted ASN.1 data and cause applications using Libtasn1 to crash, resulting in a denial of service, or possibly execute arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.10:
libtasn1-6 4.0-2ubuntu0.1

Ubuntu 14.04 LTS:
libtasn1-6 3.4-3ubuntu0.2

Ubuntu 12.04 LTS:
libtasn1-3 2.10-1ubuntu1.3

Ubuntu 10.04 LTS:
libtasn1-3 2.4-1ubuntu0.3

In general, a standard system update will make all the necessary changes.
