Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Resource management error (CVE-ID: CVE-2011-1590)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The X.509if dissector in Wireshark 1.2.x before 1.2.16 and 1.4.x before 1.4.5 does not properly initialize certain global variables, which allows remote attackers to cause a denial of service (application crash) via a crafted .pcap file.


2) Stack-based buffer overflow (CVE-ID: CVE-2011-1591)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing a crafted .pcap file. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


3) Resource management error (CVE-ID: CVE-2011-1142)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Stack consumption vulnerability in the dissect_ber_choice function in the BER dissector in Wireshark 1.2.x through 1.2.15 and 1.4.x through 1.4.4 might allow remote attackers to cause a denial of service (infinite loop) via vectors involving self-referential ASN.1 CHOICE values.
