Date: Fri, 27 Mar 2015 14:50:00 +0100 From: security@...driva.com To: bugtraq@...urityfocus.com Subject: [ MDVSA-2015:063 ] openssl -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2015:063 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : openssl Date : March 27, 2015 Affected: Business Server 1.0 _______________________________________________________________________ Problem Description: Multiple vulnerabilities has been discovered and corrected in openssl: The ssl3_get_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote SSL servers to conduct RSA-to-EXPORT_RSA downgrade attacks and facilitate brute-force decryption by offering a weak ephemeral RSA key in a noncompliant role, related to the FREAK issue. NOTE: the scope of this CVE is only client code based on OpenSSL, not EXPORT_RSA issues associated with servers or other TLS implementations (CVE-2015-0204). Use-after-free vulnerability in the d2i_ECPrivateKey function in crypto/ec/ec_asn1.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 might allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a malformed Elliptic Curve (EC) private-key file that is improperly handled during import (CVE-2015-0209). 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 (CVE-2015-0286). The ASN1_item_ex_d2i function in crypto/asn1/tasn_dec.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 reinitialize CHOICE and ADB data structures, which might allow attackers to cause a denial of service (invalid write operation and memory corruption) by leveraging an application that relies on ASN.1 structure reuse (CVE-2015-0287). The X509_to_X509_REQ function in crypto/x509/x509_req.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 might allow attackers to cause a denial of service (NULL pointer dereference and application crash) via an invalid certificate key (CVE-2015-0288). The PKCS#7 implementation 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 handle a lack of outer ContentInfo, which allows attackers to cause a denial of service (NULL pointer dereference and application crash) by leveraging an application that processes arbitrary PKCS#7 data and providing malformed data with ASN.1 encoding, related to crypto/pkcs7/pk7_doit.c and crypto/pkcs7/pk7_lib.c (CVE-2015-0289). The SSLv2 implementation 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 allows remote attackers to cause a denial of service (s2_lib.c assertion failure and daemon exit) via a crafted CLIENT-MASTER-KEY message (CVE-2015-0293). The updated packages have been upgraded to the 1.0.0r version where these security flaws has been fixed. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0204 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0209 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0286 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0287 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0288 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0289 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0293 http://openssl.org/news/secadv_20150319.txt _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: 53d5722ae81a78c5134095b4ce1ca4c1 mbs1/x86_64/lib64openssl1.0.0-1.0.0r-1.mbs1.x86_64.rpm d5f2804c2acbb03238c6873f223cb32e mbs1/x86_64/lib64openssl-devel-1.0.0r-1.mbs1.x86_64.rpm 02652b2787411a1021b5679d02537333 mbs1/x86_64/lib64openssl-engines1.0.0-1.0.0r-1.mbs1.x86_64.rpm c7370089da58f7222be84775e0e81fe0 mbs1/x86_64/lib64openssl-static-devel-1.0.0r-1.mbs1.x86_64.rpm a62309229fe9996ad36cd0f32653e3e1 mbs1/x86_64/openssl-1.0.0r-1.mbs1.x86_64.rpm 43aa60276406d5862d77001ea8504a6c mbs1/SRPMS/openssl-1.0.0r-1.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
