CVE-2020-1752 (GCVE-0-2020-1752)
Vulnerability from cvelistv5 – Published: 2020-04-30 00:00 – Updated: 2024-08-04 06:46
VLAI
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.
