========================================================================== Ubuntu Security Notice USN-1798-1 April 09, 2013
linux-ec2 vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux-ec2: Linux kernel for EC2
Details:
Mathias Krause discovered several errors in the Linux kernel's xfrm_user implementation. A local attacker could exploit these flaws to examine parts of kernel memory. (CVE-2012-6537)
Mathias Krause discovered information leak in the Linux kernel's compat ioctl interface. A local user could exploit the flaw to examine parts of kernel stack memory (CVE-2012-6539)
Mathias Krause discovered an information leak in the Linux kernel's getsockopt for IP_VS_SO_GET_TIMEOUT. A local user could exploit this flaw to examine parts of kernel stack memory. (CVE-2012-6540)
Emese Revfy discovered that in the Linux kernel signal handlers could leak address information across an exec, making it possible to by pass ASLR (Address Space Layout Randomization). A local user could use this flaw to by pass ASLR to reliably deliver an exploit payload that would otherwise be stopped (by ASLR). (CVE-2013-0914)
A memory use after free error was discover in the Linux kernel's tmpfs filesystem. A local user could exploit this flaw to gain privileges or cause a denial of service (system crash). (CVE-2013-1767)
Mateusz Guzik discovered a race in the Linux kernel's keyring. A local user could exploit this flaw to cause a denial of service (system crash). (CVE-2013-1792)
Update instructions:
