Mandriva Linux Security Advisory MDVSA-2010:089 http://www.mandriva.com/security/ _______________________________________________________________________
Package : gnutls Date : May 3, 2010 Affected: Corporate 4.0 _______________________________________________________________________
Problem Description:
Multiple vulnerabilities has been found and corrected in gnutls: The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a plaintext injection attack, aka the Project Mogul issue (CVE-2009-3555). The gnutls_x509_crt_get_serial function in the GnuTLS library before 1.2.1, when running on big-endian, 64-bit platforms, calls the asn1_read_value with a pointer to the wrong data type and the wrong length value, which allows remote attackers to bypass the certificate revocation list (CRL) check and cause a stack-based buffer overflow via a crafted X.509 certificate, related to extraction of a serial number (CVE-2010-0731). The updated packages have been patched to correct these issues. _______________________________________________________________________
