Scientific Linux Security Update : libtasn1 on SL6.x i386/x86_64 (20140603)

medium Nessus Plugin ID 74307

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

It was discovered that the asn1_get_bit_der() function of the libtasn1 library incorrectly reported the length of ASN.1-encoded data.
Specially crafted ASN.1 input could cause an application using libtasn1 to perform an out-of-bounds access operation, causing the application to crash or, possibly, execute arbitrary code.
(CVE-2014-3468)

Multiple incorrect buffer boundary check issues were discovered in libtasn1. Specially crafted ASN.1 input could cause an application using libtasn1 to crash. (CVE-2014-3467)

Multiple NULL pointer dereference flaws were found in libtasn1's asn1_read_value() function. Specially crafted ASN.1 input could cause an application using libtasn1 to crash, if the application used the aforementioned function in a certain way. (CVE-2014-3469)

For the update to take effect, all applications linked to the libtasn1 library must be restarted.

Solution

Update the affected packages.
