Vulnerability identifier: #VU95634

Vulnerability risk: Low

CVSSv3.1: 4.6 [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-2005-2872

CWE-ID: CWE-399

Exploitation vector: Network

Exploit availability: No

Vulnerable software:
Linux kernel
Operating systems & Components / Operating system

Vendor: Linux Foundation

Description

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

The ipt_recent kernel module (ipt_recent.c) in Linux kernel before 2.6.12, when running on 64-bit processors such as AMD64, allows remote attackers to cause a denial of service (kernel panic) via certain attacks such as SSH brute force, which leads to memset calls using a length based on the u_int32_t type, acting on an array of unsigned long elements, a different vulnerability than CVE-2005-2873.

Mitigation
Install update from vendor's repository.
