linux-source-2.6.15 vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 6.06 LTS
Summary
Multiple vulnerabilities in Linux kernel.
Software description
- linux-source-2.6.15 - ACPI support modules (udeb)
Details
Dave Chinner discovered that the XFS filesystem did not correctly order
inode lookups when exported by NFS. A remote attacker could exploit this to
read or write disk blocks that had changed file assignment or had become
unlinked, leading to a loss of privacy. (CVE-2010-2943)
Dan Rosenberg discovered that several network ioctls did not clear kernel
memory correctly. A local user could exploit this to read kernel stack
memory, leading to a loss of privacy. (CVE-2010-3297)
Kees Cook and Vasiliy Kulikov discovered that the shm interface did not
clear kernel memory correctly. A local attacker could exploit this to read
kernel stack memory, leading to a loss of privacy. (CVE-2010-4072)
