USN-2071-1: Linux kernel vulnerabilities

Published Jan 3, 2014
·
Updated

Dave Jones and Vince Weaver reported a flaw in the Linux kernel's per event subsystem that allows normal users to enable function tracing. An unprivileged local user could exploit this flaw to obtain potentially sensitive information from the kernel. (CVE-2013-2930) Stephan Mueller reported an error in the Linux kernel's ansi cprng random number generator. This flaw makes it easier for a local attacker to break cryptographic protections. (CVE-2013-4345) Multiple integer overflow flaws were discovered in the Alchemy LCD frame- buffer drivers in the Linux kernel. An unprivileged local user could exploit this flaw to gain administrative privileges. (CVE-2013-4511) Nico Golde and Fabian Yamaguchi reported a buffer overflow in the Ozmo Devices USB over WiFi devices. A local user could exploit this flaw to cause a denial of service or possibly unspecified impact. (CVE-2013-4513) Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel's driver for Agere Systems HERMES II Wireless PC Cards. A local user with the CAPNETADMIN capability could exploit this flaw to cause a denial of service or possibly gain adminstrative priviliges. (CVE-2013-4514) Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel's driver for Beceem WIMAX chipset based devices. An unprivileged local user could exploit this flaw to obtain sensitive information from kernel memory. (CVE-2013-4515) A flaw was discovered in the Linux kernel's compat ioctls for Adaptec AACRAID scsi raid devices. An unprivileged local user could send administrative commands to these devices potentially compromising the data stored on the device. (CVE-2013-6383) Nico Golde reported a flaw in the Linux kernel's userspace IO (uio) driver. A local user could exploit this flaw to cause a denial of service (memory corruption) or possibly gain privileges. (CVE-2013-6763) Evan Huus reported a buffer overflow in the Linux kernel's radiotap header parsing. A remote attacker could cause a denial of service (buffer over- read) via a specially crafted header. (CVE-2013-7027)
