Description
bz2.BZ2Decompressor objects can be reused following a decompression error. If an application catches the resulting OSError and attempts to retry using the same decompressor, specially crafted input may cause the decompressor to resume from an invalid internal state. This leads to out-of-bounds writes to a stack buffer, which can result in a process crash when processing untrusted data.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
