CVE-2019-14876

Name of the Vulnerable Software and Affected Versions newlib libc library versions prior to 3.3.0

Description The issue arises in the lshift function of the newlib libc library, where memory allocation using Balloc for a big integer does not include a check for allocation success. This oversight can lead to a null pointer dereference bug if memory allocation fails, as access to b1 will be attempted without verifying if the allocation was successful.

Recommendations For versions prior to 3.3.0, update to version 3.3.0 or later to resolve the issue.
