Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to usage of an untrusted LD_LIBRARY_PATH environment variable. A local user can use the LD_LIBRARY_PATH environment variable to point to a malicious binary and execute arbitrary code with escalated privileges.

The vulnerability affects statically linked setuid binaries that call dlopen (including internal dlopen calls after setlocale or calls to NSS functions such as getaddrinfo).

Mitigation

Install updates from vendor's website.
