New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis

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

Description

A flaw was found in the way GnuTLS parsed session IDs from ServerHello messages of the TLS/SSL handshake. A malicious server could use this flaw to send an excessively long session ID value, which would trigger a buffer overflow in a connecting TLS/SSL client application using GnuTLS, causing the client application to crash or, possibly, execute arbitrary code. (CVE-2014-3466)

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 GnuTLS or libtasn1 library must be restarted.

Solution

Update the affected packages.
