Security Bulletin

This security bulletin contains one high risk vulnerability.

1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU45489

Risk: High

CVSSv4.0: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber]

CVE-ID: CVE-2010-3856

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: Yes

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

ld.so in the GNU C Library (aka glibc or libc6) before 2.11.3, and 2.12.x before 2.12.2, does not properly restrict use of the LD_AUDIT environment variable to reference dynamic shared objects (DSOs) as audit objects, which allows local users to gain privileges by leveraging an unsafe DSO located in a trusted library directory, as demonstrated by libpcprofile.so.

Mitigation

Update the affected package glibc.

Vulnerable software versions

Slackware Linux: 13.0 - 13.1
