Details

As written in the advisory (Markdown source, shown as plain text).

An issue was discovered in py-lmdb 0.97. For certain values of `mp_flags`, `mdb_page_touch `does not properly set up `mc->mc_pg[mc->top]`, leading to an invalid write operation. NOTE: this outcome occurs when accessing a `data.mdb` file supplied by an attacker.
