CVE-2023-30571 (GCVE-0-2023-30571)

Vulnerability from cvelistv5 – Published: 2023-05-29 00:00 – Updated: 2025-01-14 17:07
VLAI
Summary
Libarchive through 3.6.2 can cause directories to have world-writable permissions. The umask() call inside archive_write_disk_posix.c changes the umask of the whole process for a very short period of time; a race condition with another thread can lead to a permanent umask 0 setting. Such a race condition could lead to implicit directory creation with permissions 0777 (without the sticky bit), which means that any low-privileged local user can delete and rename files inside those directories.
Severity
