Description
This security bulletin contains information about 1 security vulnerability.
1) Memory corruption (CVE-ID: CVE-2006-6333)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The tr_rx function in ibmtr.c for Linux kernel 2.6.19 assigns the wrong flag to the ip_summed field, which allows remote attackers to cause a denial of service (memory corruption) via crafted packets that cause the kernel to interpret another field as an offset.
Remediation
Install update from vendor's website.
