Description

This security bulletin contains information about 1 vulnerability.


1) Memory corruption (CVE-ID: CVE-2018-11236)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local attacker to gain elevated privileges on the target system.

The vulnerability exists in the stdlib/canonicalize.c source code in the GNU glibc library due to improper processing of long pathname arguments to the realpath function. A local unauthenticated attacker can send long pathname arguments to a targeted system that is using 32-bit architecture, trigger an integer overflow condition that can lead to stack-based buffer overflow condition and execute arbitrary code with elevated privileges.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
