CVE-2012-6548 [LOW] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the kernel.
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
