Name of the Vulnerable Software and Affected Versions Zstandard versions prior to 1.3.8

Description A race condition in the one-pass compression functions could allow an attacker to write bytes out of bounds if an output buffer smaller than the recommended size was used. The vulnerability is related to errors in synchronization when using a shared resource, which can be exploited by a remote attacker to execute arbitrary code.

Recommendations For versions prior to 1.3.8, update to version 1.3.8 or later to resolve the issue. As a temporary workaround, consider using output buffers of the recommended size or larger to minimize the risk of exploitation.
