Name of the Vulnerable Software and Affected Versions py-lmdb version 0.97

Description An issue was discovered in py-lmdb where for certain values of md flags, the mdb node add function does not properly set up a memcpy destination, leading to an invalid write operation. This issue occurs when accessing a data.mdb file supplied by an attacker.

Recommendations For py-lmdb version 0.97, consider restricting access to untrusted data.mdb files until a patch is available. As a temporary workaround, avoid using the mdb node add function with unverified input.
