CVE-2020-1752
A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde expansion was carried out.
Impact
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.
