CVE-2015-0286

Status Candidate

Overview

The ASN1_TYPE_cmp function in crypto/asn1/a_type.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not properly perform boolean-type comparisons, which allows remote attackers to cause a denial of service (invalid read operation and application crash) via a crafted X.509 certificate to an endpoint that uses the certificate-verification feature.

Red Hat Security Advisory 2015-0752-01 - OpenSSL is a toolkit that implements the Secure Sockets Layer and Transport Layer Security protocols, as well as a full-strength, general purpose cryptography library. An invalid pointer use flaw was found in OpenSSL's ASN1_TYPE_cmp() function. A remote attacker could crash a TLS/SSL client or server using OpenSSL via a specially crafted X.509 certificate when the attacker-supplied certificate was verified by the application. An integer underflow flaw, leading to a buffer overflow, was found in the way OpenSSL decoded malformed Base64-encoded inputs. An attacker able to make an application using OpenSSL decode a specially crafted Base64-encoded input could use this flaw to cause the application to crash. Note: this flaw is not exploitable via the TLS/SSL protocol because the data being transferred is not Base64-encoded.

FreeBSD Security Advisory - OpenSSL Issues
Posted Mar 20, 2015
Site security.freebsd.org

FreeBSD Security Advisory - Multiple OpenSSL issues have been resolved. A malformed elliptic curve private key file could cause a use-after-free condition in the d2i_ECPrivateKey function. An attempt to compare ASN.1 boolean types will cause the ASN1_TYPE_cmp function to crash with an invalid read. Reusing a structure in ASN.1 parsing may allow an attacker to cause memory corruption via an invalid write. The function X509_to_X509_REQ will crash with a NULL pointer dereference if the certificate key is invalid. The PKCS#7 parsing code does not handle missing outer ContentInfo correctly. A malicious client can trigger an OPENSSL_assert in servers that both support SSLv2 and enable export cipher suites by sending a specially crafted SSLv2 CLIENT-MASTER-KEY message.
