CVE-2018-14043 (GCVE-0-2018-14043)

Vulnerability from cvelistv5 – Published: 2018-07-13 14:00 – Updated: 2024-09-16 16:22

Summary

mstdlib (aka the M Standard Library for C) 1.2.0 has incorrect file access control in situations where M_fs_perms_can_access attempts to delete an existing file (that lacks public read/write access) during a copy operation, related to fs/m_fs.c and fs/m_fs_path.c. An attacker could create the file and then would have access to the data.

Severity

No CVSS data available.
