CVE-2020-1752 (GCVE-0-2020-1752)

Vulnerability from cvelistv5

Published

2020-04-30 00:00

Modified

2024-08-04 06:46

Severity ?

7.0 (High) - CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H

CWE

CWE-416

Summary

A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde expansion was carried out. Directory paths containing an initial tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path that, when processed by the glob function, would potentially lead to arbitrary code execution. This was fixed in version 2.32.
