CVE-2019-5606 (GCVE-0-2019-5606)

Vulnerability from cvelistv5 – Published: 2019-07-26 00:33 – Updated: 2024-08-04 20:01

Summary

In FreeBSD 12.0-STABLE before r349805, 12.0-RELEASE before 12.0-RELEASE-p8, 11.3-STABLE before r349806, 11.3-RELEASE before 11.3-RELEASE-p1, and 11.2-RELEASE before 11.2-RELEASE-p12, code which handles close of a descriptor created by posix_openpt fails to undo a signal configuration. This causes an incorrect signal to be raised leading to a write after free of kernel memory allowing a malicious user to gain root privileges or escape a jail.

Severity

No CVSS data available.

CWE
