Security Bulletin
This security bulletin contains one medium risk vulnerability.
1) Buffer overflow
EUVDB-ID: #VU32605
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2013-4081
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to perform service disruption.
The http_payload_subdissector function in epan/dissectors/packet-http.c in the HTTP dissector in Wireshark 1.6.x before 1.6.16 and 1.8.x before 1.8.8 does not properly determine when to use a recursive approach, which allows remote attackers to cause a denial of service (stack consumption) via a crafted packet.
MitigationInstall update from vendor's website.
Vulnerable software versionsWireshark: 1.6.0 - 1.6.15
