CVE-2020-1752: Canonical Ubuntu Linux

High severity, CVSS 7.0. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

• Canonical Ubuntu Linux: version 16.04 only; version 18.04 only; version 19.10 only
• Debian Debian Linux: version 10.0 only
