Description
This security bulletin contains information about 1 security vulnerability.
1) Missing release of memory after effective lifetime (CVE-ID: CVE-2005-3848)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
Memory leak in the icmp_push_reply function in Linux 2.6 before 2.6.12.6 and 2.6.13 allows remote attackers to cause a denial of service (memory consumption) via a large number of crafted packets that cause the ip_append_data function to fail, aka 'DST leak in icmp_push_reply.'
Remediation
Install update from vendor's website.
