Description Martin Prpič 2015-03-17 13:15:12 UTC
The following flaw was found in python-dulwich:

Ivan Fratric of the Google Security Team has found a buffer overflow in the C implementation of the apply_delta() function in Dulwich. This function is used when accessing Git objects in pack files. Any Git server or client based on Dulwich that handles untrusted pack files is very likely to be vulnerable.

This issue has been assigned CVE-2015-0838.
