EUVDB-ID: #VU26628

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-1752

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error within the glob() function in glibc in the way the tilde expansion was carried out. Directory paths containing an initial tilde followed by a valid username are affected by this issue. A local user can create a specially crafted path that, when processed by the glob() function, would potentially lead to arbitrary code execution.

Mitigation

Install update from vendor's website.
