CVE-2016-5636 (opens in a new tab)How to fix?
Upgrade SLES:15.1 python-devel to version 2.7.17-7.32.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python-devel package and not the python-devel package as distributed by SLES.
See How to fix? for SLES:15.1 relevant fixed versions and status.
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.
