A buffer overflow in Python might allow remote attackers to execute arbitrary code.

Affected Packages

dev-lang/python on all architectures
Affected versions < 2.7.14
Unaffected versions >= 2.7.14

Background

Python is an interpreted, interactive, object-oriented programming language.

Description

A buffer overflow was discovered in Python’s PyString_DecodeEscape function in stringobject.c.

Impact

Remote attackers, by enticing a user to process a specially crafted file, could execute arbitrary code.

Workaround

There is no known workaround at this time.

Resolution

All Python 2 users should upgrade to the latest version:
