Kerentanan Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') pada libarchive. Skor CVSS 3.1 5.3 (Medium) menurut NVD.

Deskripsi (NVD)

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.
