#VU41284 Resource management error in Linux kernel - CVE-2014-6410

Vulnerability identifier: #VU41284

Vulnerability risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2014-6410

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 a denial of service (DoS) attack.

The __udf_read_inode function in fs/udf/inode.c in the Linux kernel through 3.16.3 does not restrict the amount of ICB indirection, which allows physically proximate attackers to cause a denial of service (infinite loop or stack consumption) via a UDF filesystem with a crafted inode.

Mitigation
Install update from vendor's website.

Vulnerable software versions

Linux kernel: 3.16.0 - 3.16.2
