Fedora 24: Critical Heap Problem in FEDORA-2017-08207fe48b Alert

fedora
Calendar Grey January 30, 2017
Scroller Fedora
Buffer overflow in Crypto library exposes users using ECB mode, necessitating immediate patching to prevent unauthorized code execution.
A heap-buffer overflow vulnerability was discovered in pycrypto leading to arbitrary code execution

Summary

PyCrypto is a collection of both secure hash functions (such as MD5 and

SHA), and various encryption algorithms (AES, DES, RSA, ElGamal, etc.).

Update Information:

A heap-buffer overflow vulnerability was discovered in pycrypto leading to arbitrary code execution. All users of pycrypto's AES module that allow the mode of operation to be specified by an attacker, check for ECB explicitly and create the objects without specifying an IV are vulnerable to this issue. This is CVE-2013-7459.
