CVE-2017-7487

Status Candidate

Overview

The ipxitf_ioctl function in net/ipx/af_ipx.c in the Linux kernel through 4.11.1 mishandles reference counts, which allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a failed SIOCGIFADDR ioctl call for an IPX interface.

Ubuntu Security Notice 3344-1 - USN 3328-1 fixed a vulnerability in the Linux kernel. However, that fix introduced regressions for some Java applications. This update addresses the issue. Roee Hay discovered that the parallel port printer driver in the Linux kernel did not properly bounds check passed arguments. A local attacker with write access to the kernel command line arguments could use this to execute arbitrary code. Various other issues were also addressed.
