CVE-2012-6549

Published: 15 March 2013

The isofs_export_encode_fh function in fs/isofs/export.c in the Linux kernel before 3.6 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel heap memory via a crafted application.

From the Ubuntu security team

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.
