Fixed In Version: openssl 1.0.2a, openssl 1.0.1m, openssl 1.0.0r, openssl 0.9.8zf
Doc Type: Bug Fix
Doc Text:
A NULL pointer dereference was found in the way OpenSSL handled certain PKCS#7 inputs. An attacker able to make an application using OpenSSL verify, decrypt, or parse a specially crafted PKCS#7 input could cause that application to crash. TLS/SSL clients and servers using OpenSSL were not affected by this flaw.

Description Martin Prpič 2015-03-16 14:11:21 UTC 
The PKCS#7 parsing code does not handle missing outer ContentInfo correctly. An attacker can craft malformed ASN.1-encoded PKCS#7 blobs with missing content and trigger a NULL pointer dereference on parsing.

Applications that verify PKCS#7 signatures, decrypt PKCS#7 data or otherwise parse PKCS#7 structures from untrusted sources are affected. OpenSSL clients and servers are not affected.

This issue affects OpenSSL versions: 1.0.2, 1.0.1, 1.0.0, and 0.9.8. This issue is fixed in versions: 1.0.2a, 1.0.1m, 1.0.0r, and 0.9.8zf.

Note there is also https://rt.openssl.org/Ticket/Display.html?id=3339&user=guest&pass=guest which is related and I want to fix it along with these changes to pkcs7 handling.
