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
mn flags, mdb cursor set triggers a memcpy with an invalid write operation within mdb xcursor init1. This issue occurs when accessing a data.mdb file supplied by an attacker.Recommendations
For py-lmdb version 0.97, consider restricting access to the
mdb cursor set function until a patch is available, especially when handling data.mdb files from untrusted sources. As a temporary workaround, avoid using certain values of mn flags that trigger the invalid write operation within mdb xcursor init1.Exploit
