CVE-2018-14939 (GCVE-0-2018-14939)

Vulnerability from cvelistv5 – Published: 2018-08-05 18:00 – Updated: 2024-08-05 09:46

Summary

The get_app_path function in desktop/unx/source/start.c in LibreOffice through 6.0.5 mishandles the realpath function in certain environments such as FreeBSD libc, which might allow attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact if LibreOffice is automatically launched during web browsing with pathnames controlled by a remote web site.

Severity
