Echo: libarchive: security update to 3.7.4-4

medium Tenable Cloud Security Plugin ID 461290

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2023-30571)

Solution

Update the libarchive library and its related packages to version 3.7.4-4 or later.
