Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Resource management error (CVE-ID: CVE-2012-5237)

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

The dissect_hsrp function in epan/dissectors/packet-hsrp.c in the HSRP dissector in Wireshark 1.8.x before 1.8.3 allows remote attackers to cause a denial of service (infinite loop) via a malformed packet.


2) Input validation error (CVE-ID: CVE-2012-5238)

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

epan/dissectors/packet-ppp.c in the PPP dissector in Wireshark 1.8.x before 1.8.3 uses incorrect OUI data structures during the decoding of (1) PPP and (2) LCP data, which allows remote attackers to cause a denial of service (assertion failure and application exit) via a malformed packet.


3) Buffer overflow (CVE-ID: CVE-2012-5240)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Buffer overflow in the dissect_tlv function in epan/dissectors/packet-ldp.c in the LDP dissector in Wireshark 1.8.x before 1.8.3 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a malformed packet.


4) Resource management error (CVE-ID: CVE-2012-3548)

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

The dissect_drda function in epan/dissectors/packet-drda.c in Wireshark 1.6.x through 1.6.10 and 1.8.x through 1.8.2 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a small value for a certain length field in a capture file.
