Name of the Vulnerable Software and Affected Versions libarchive versions prior to 3.2.0

Description The issue is related to multiple integer overflows in the get time t max and get time t min functions in archive read support format mtree.c. This can be triggered by a crafted mtree file, leading to undefined behavior. The estimated number of potentially affected devices and details about real-world incidents are not specified.

Recommendations For versions prior to 3.2.0, update to version 3.2.0 or later to resolve the issue. As a temporary workaround, consider restricting the use of the get time t max and get time t min functions in archive read support format mtree.c until a patch is available.
