DSA-1844 linux-2.6.24 -- denial of service/privilege escalation

ID: oval:org.mitre.oval:def:8024Date: (C)2009-12-15   (M)2024-02-19
Class: PATCHFamily: unix




Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems: Neil Horman discovered a missing fix from the e1000 network driver. A remote user may cause a denial of service by way of a kernel panic triggered by specially crafted frame sizes. Michael Tokarev discovered an issue in the r8169 network driver. Remote users on the same LAN may cause a denial of service by way of a kernel panic triggered by receiving a large size frame. Frank Filz discovered that local users may be able to execute files without execute permission when accessed via an nfs4 mount. Jeff Layton and Suresh Jayaraman fixed several buffer overflows in the CIFS filesystem which allow remote servers to cause memory corruption. Julien Tinnes and Tavis Ormandy reported an issue in the Linux personality code. Local users can take advantage of a setuid binary that can either be made to dereference a NULL pointer or drop privileges and return control to the user. This allows a user to bypass mmap_min_addr restrictions which can be exploited to execute arbitrary code. Mikulas Patocka discovered an issue in sparc64 kernels that allows local users to cause a denial of service (crash) by reading the /proc/iomem file. Miklos Szeredi reported an issue in the ocfs2 filesystem. Local users can create a denial of service (filesystem deadlock) using a particular sequence of splice system calls. Ramon de Carvalho Valle discovered two issues with the eCryptfs layered filesystem using the fsfuzzer utility. A local user with permissions to perform an eCryptfs mount may modify the contents of a eCryptfs file, overflowing the stack and potentially gaining elevated privileges.
