linux-source-2.6.8.1 vulnerabilities Detailed Explanation for this Vulnerability Assessment Summary : These remote packages are missing security patches : - linux-doc-2.6.8.1 - linux-headers-2.6.8.1-5 - linux-headers-2.6.8.1-5-386 - linux-headers-2.6.8.1-5-686 - linux-headers-2.6.8.1-5-686-smp - linux-headers-2.6.8.1-5-amd64-generic - linux-headers-2.6.8.1-5-amd64-k8 - linux-headers-2.6.8.1-5-amd64-k8-smp - linux-headers-2.6.8.1-5-amd64-xeon - linux-headers-2.6.8.1-5-k7 - linux-headers-2.6.8.1-5-k7-smp - linux-headers-2.6.8.1-5-power3 - linux-headers-2.6.8.1-5-power3-smp - linux-headers-2.6.8. [...] Description : A remote Denial of Service vulnerability was discovered in the Netfilter IP packet handler. This permited a remote attacker to crash the machine by sending specially crafted IP packet fragments. (CVE-2005-0209) The Netfilter code also contained a memory leak. Certain locally generated packet fragments are reassembled twice, which caused a double allocation of a data structure. This could be locally exploited to crash the machine due to kernel memory exhaustion. (CVE-2005-0210) Ben Martel and Stephen Blackheath found a remote Denial of Service vulnerability in the PPP driver. This permited a malicious pppd client to crash the server machine. (CVE-2005-0384) Georgi Guninski discovered a buffer overflow in the ATM driver. The atm_get_addr() function does not validate its arguments sufficiently, which could permit a local attacker to overwrite large portions of kernel memory by supplying a negative length argument. This could eventually lead to arbitrary code execution. (CVE-2005-0531) Georgi Guninski also disc [...] Solution : Upgrade to : - linux-doc-2.6.8.1-2.6.8.1-16.12 (Ubuntu 4.10) - linux-headers-2.6.8.1-5-2.6.8.1-16.12 (Ubuntu 4.10) - linux-headers-2.6.8.1-5-386-2.6.8.1-16.12 (Ubuntu 4.10) - linux-headers-2.6.8.1-5-686-2.6.8.1-16.12 (Ubuntu 4.10) - linux-headers-2.6.8.1-5-686-smp-2.6.8.1-16.12 (Ubuntu 4.10) - linux-headers-2.6.8.1-5-amd64-generic-2.6.8.1-16.12 (Ubuntu 4.10) - linux-headers-2.6.8.1-5-amd64-k8-2.6.8.1-16.12 (Ubuntu 4.10) - linux-headers-2.6.8.1-5-amd64-k8-smp-2.6.8.1-16.12 (Ubuntu 4.10) - linux-headers-2.6 [...] Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: Ubuntu Security Notice (C) 2005 Canonical, Inc. / NASL script (C) 2005 Michel Arboi |
