Ubuntu Update for Linux kernel vulnerabilities USN-578-1

Please Install the Updated Packages.

The minix filesystem did not properly validate certain filesystem values. If a local attacker could trick the system into attempting to mount a corrupted minix filesystem, the kernel could be made to hang for long periods of time, resulting in a denial of service. (CVE-2006-6058) Alexander Schulze discovered that the skge driver does not properly use the spin_lock and spin_unlock functions. Remote attackers could exploit this by sending a flood of network traffic and cause a denial of service (crash). (CVE-2006-7229) Hugh Dickins discovered that hugetlbfs performed certain prio_tree calculations using HPAGE_SIZE instead of PAGE_SIZE. A local user could exploit this and cause a denial of service via kernel panic. (CVE-2007-4133) Chris Evans discovered an issue with certain drivers that use the ieee80211_rx function. Remote attackers could send a crafted 802.11 frame and cause a denial of service via crash. (CVE-2007-4997) Alex Smith discovered an issue with the pwc driver for certain webcam devices. A local user with physical access to the system could remove the device while a userspace application had it open and cause the USB subsystem to block. (CVE-2007-5093) Scott James Remnant discovered a coding error in ptrace. Local users could exploit this and cause the kernel to enter an infinite loop. (CVE-2007-5500) Venustech AD-LAB discovered a buffer overflow in the isdn net subsystem. This issue is exploitable by local users via crafted input to the isdn_ioctl function. (CVE-2007-6063) It was discovered that the isdn subsystem did not properly check for NULL termination when performing ioctl handling. A local user could exploit this to cause a denial of service. (CVE-2007-6151) Blake Frantz discovered that when a root process overwrote an existing core file, the resulting core file retained the previous core file's ownership. Local users could exploit this to gain access to sensitive information. (CVE-2007-6206) Hugh Dickins discovered the when using the tmpfs filesystem, under rare circumstances, a kernel page may be improperly cleared. A local user may be able to exploit this and read sensitive kernel data or cause a denial of service via crash. (CVE-2007-6417) Bill Roman discovered that the VFS subsystem did not properly check access modes. A local user may be able to gain removal privileges on directories. (CVE-2008-0001)
