USN-1813-1: Linux kernel vulnerabilities

First published: Thu May 02 2013(Updated: )

Mathias Krause discovered an information leak in the Linux kernel's UDF file system implementation. A local user could exploit this flaw to examine some of the kernel's heap memory. (CVE-2012-6548) Mathias Krause discovered an information leak in the Linux kernel's ISO 9660 CDROM file system driver. A local user could exploit this flaw to examine some of the kernel's heap memory. (CVE-2012-6549) An integer overflow was discovered in the Direct Rendering Manager (DRM) subsystem for the i915 video driver in the Linux kernel. A local user could exploit this flaw to cause a denial of service (crash) or potentially escalate privileges. (CVE-2013-0913) Andrew Honig discovered a flaw in guest OS time updates in the Linux kernel's KVM (Kernel-based Virtual Machine). A privileged guest user could exploit this flaw to cause a denial of service (crash host system) or potential escalate privilege to the host kernel level. (CVE-2013-1796) Andrew Honig discovered a use after free error in guest OS time updates in the Linux kernel's KVM (Kernel-based Virtual Machine). A privileged guest user could exploit this flaw to escalate privilege to the host kernel level. (CVE-2013-1797) Andrew Honig reported a flaw in the way KVM (Kernel-based Virtual Machine) emulated the IOAPIC. A privileged guest user could exploit this flaw to read host memory or cause a denial of service (crash the host). (CVE-2013-1798) A format-string bug was discovered in the Linux kernel's ext3 filesystem driver. A local user could exploit this flaw to possibly escalate privileges on the system. (CVE-2013-1848) A buffer overflow was discovered in the Linux Kernel's USB subsystem for devices reporting the cdc-wdm class. A specially crafted USB device when plugged-in could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2013-1860) A flaw was discovered in the SCTP (stream control transfer protocol) network protocol's handling of duplicate cookies in the Linux kernel. A remote attacker could exploit this flaw to cause a denial of service (system crash) on another remote user querying the SCTP connection. (CVE-2013-2206) An information leak in the Linux kernel's dcb netlink interface was discovered. A local user could obtain sensitive information by examining kernel stack memory. (CVE-2013-2634) A kernel stack information leak was discovered in the RTNETLINK component of the Linux kernel. A local user could read sensitive information from the kernel stack. (CVE-2013-2635)
