Vulnerability CVE-2014-3074
Published: 2014-07-02

Description:
The runtime linker in IBM AIX 6.1 and 7.1 and VIOS 2.2.x allows local users to create a mode-666 root-owned file, and consequently gain privileges, by setting crafted MALLOCOPTIONS and MALLOCBUCKETS environment-variable values and then executing a setuid program.
