CVE-2012-6549 [LOW] Linux kernel (EC2) vulnerabilities
Title: Linux kernel (EC2) vulnerabilities
Summary: Several security issues were fixed in the kernel.
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)
Mathias Krause discovered a flaw in xfrm_user in the Linux kernel. A local
attacker with NET_ADMIN capability could potentially exploit this flaw to
escalate privileges. (CVE-2013-1826)
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)
