CVSSv4.0: 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
Exploitation vector: Remote access
Exploit availability: Public exploit is available
Vulnerable software:
Glibc
Software vendor:
GNU

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.


Remediation

Install update from vendor's website.
