EUVDB-ID: #VU32364
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-2015-7830
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to perform service disruption.
The pcapng_read_if_descr_block function in wiretap/pcapng.c in the pcapng parser in Wireshark 1.12.x before 1.12.8 uses too many levels of pointer indirection, which allows remote attackers to cause a denial of service (incorrect free and application crash) via a crafted packet that triggers interface-filter copying.
MitigationInstall update from vendor's website.
Vulnerable software versionsWireshark: 1.12.0 - 1.12.7
