Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Resource management error (CVE-ID: CVE-2011-1957)

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

The dissect_dcm_main function in epan/dissectors/packet-dcm.c in the DICOM dissector in Wireshark 1.2.x before 1.2.17 and 1.4.x before 1.4.7 allows remote attackers to cause a denial of service (infinite loop) via an invalid PDU length.


2) Input validation error (CVE-ID: CVE-2011-1958)

The vulnerability allows user-assisted remote attackers to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (NULL pointer dereference and application crash) via a crafted Diameter dictionary file.


3) Stack-based buffer overflow (CVE-ID: CVE-2011-1959)

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

The vulnerability exists due to a boundary error within the snoop_read function in wiretap/snoop.c when processing a large length value in a snoop file that triggers a stack-based buffer over-read. 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.


4) Resource management error (CVE-ID: CVE-2011-2174)

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

Double free vulnerability in the tvb_uncompress function in epan/tvbuff.c in Wireshark 1.2.x before 1.2.17 and 1.4.x before 1.4.7 allows remote attackers to cause a denial of service (application crash) via a packet with malformed data that uses zlib compression.


5) Out-of-bounds read (CVE-ID: CVE-2011-2175)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in Integer underflow in the visual_read function in wiretap/visual.c in Wireshark 1.2.x before 1.2.17 and 1.4.x before 1.4.7. A remote attacker can perform a denial of service (application crash) via a malformed Visual Networks file that triggers a heap-based buffer over-read.
