CVE-2010-3067

Published: 21 September 2010

Integer overflow in the do_io_submit function in fs/aio.c in the Linux kernel before 2.6.36-rc4-next-20100915 allows local users to cause a denial of service or possibly have unspecified other impact via crafted use of the io_submit system call.

From the Ubuntu Security Team

Tavis Ormandy discovered that the AIO subsystem did not correctly validate certain parameters. A local attacker could exploit this to crash the system or possibly gain root privileges.
