Several local vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2006-6058 LMH reported an issue in the minix filesystem that allows local users with mount privileges to create a DoS (printk flood) by mounting a specially crafted corrupt filesystem. CVE-2007-5966 Warren Togami discovered an issue in the hrtimer subsystem that allows a local user to cause a DoS (soft lockup) by requesting a timer sleep for a long period of time leading to an integer overflow. CVE-2007-6063 Venustech AD-LAB discovered a a buffer overflow in the isdn ioctl handling, exploitable by a local user. CVE-2007-6206 Blake Frantz discovered that when a core file owned by a non-root user exists, and a root-owned process dumps core over it, the core file retains its original ownership. This could be used by a local user to gain access to sensitive information. CVE-2007-6417 Hugh Dickins discovered an issue in the tmpfs filesystem where, under a rare circumstance, a kernel page maybe improperly cleared, leaking sensitive kernel memory to userspace or resulting in a DoS (crash). These problems have been fixed in the stable distribution in version 2.6.18.dfsg.1-13etch6. The following matrix lists additional packages that were rebuilt for compatability with or to take advantage of this update: Debian 4.0 (etch) fai-kernels 1.17+etch.13etch6 user-mode-linux 2.6.18-1um-2etch.13etch6 We recommend that you upgrade your kernel package immediately and reboot
