Description
This security bulletin contains information about 1 vulnerability.
1) Input validation error (CVE-ID: CVE-2013-3556)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The fragment_add_seq_common function in epan/reassemble.c in the ASN.1 BER dissector in Wireshark before r48943 has an incorrect pointer dereference during a comparison, which allows remote attackers to cause a denial of service (application crash) via a malformed packet.
Remediation
Install update from vendor's website.
