Vulnerability description

DayBreach CVE AI Research

CVE-2020-1752 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.

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.
