CVE-2016-5636
Published: 2 September 2016
Integer overflow in the get_data function in zipimport.c in CPython (aka Python) before 2.7.12, 3.x before 3.4.5, and 3.5.x before 3.5.2 allows remote attackers to have unspecified impact via a negative data size value, which triggers a heap-based buffer overflow.
Notes
Author | Note |
---|---|
sbeattie | issue is fixed for xenial/python3.5 and xenial/python2.7 for packages in xenial-updates, but not xenial-security may also need https://hg.python.org/cpython/rev/2edbdb79cd6d (see comment on python bug above) for pre-2.7.8 code and possibly 3.x code. |
