CVE-2014-0930

Status Candidate

Overview

The ptrace system call in IBM AIX 5.3, 6.1, and 7.1, and VIOS 2.2.x, allows local users to cause a denial of service (system crash) or obtain sensitive information from kernel memory via a crafted PT_LDINFO operation.

IBM AIX Kernel Memory Leak / Denial Of Service
Posted May 6, 2014
Authored by Tim Brown | Site portcullis-security.com

IBM AIX versions 5.3, 6.1 and 7.1 releases VIOS 2.2.* suffer from kernel memory leak and denial of service vulnerabilities. It has been identified that the ptrace() system call can be manipulated by an unprivileged user into leaking uninitialized kernel memory and that the method by which this is achieved may also lead to a denial of service condition. This can be achieved by manipulating the parameters that are passed to the ptrace() system call when performing the PT_LDINFO operation. By calling ptrace(PT_LDINFO, childpid, leakbuffer, maximumleak, NULL) with a value of maximumleak that greater than that required for the expected result of the PT_LDINFO operation, the AIX kernel will xmalloc() this space (without initializing it), populate it and then perform a copy operation that returns the result within leakbuffer.
