The SMB implementation in the Server service in Microsoft Windows 2000 SP4, Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista Gold, SP1, and SP2, Windows Server 2008 Gold, SP2, and R2, and Windows 7 does not use a sufficient source of entropy, which allows remote attackers to obtain access to files and other SMB resources via a large number of authentication requests, related to server-generated challenges, certain "duplicate values," and spoofing of an authentication token, aka "SMB NTLM Authentication Lack of Entropy Vulnerability."

Zeacom Chat Server before 5.1 uses too short a random string for the JSESSIONID value, which makes it easier for remote attackers to hijack sessions or cause a denial of service (Chat Server crash or Tomcat daemon crash) via a brute-force attack.

Open Directory in Apple Mac OS X 10.6 before 10.6.4 creates an unencrypted connection upon certain SSL failures, which allows man-in-the-middle attackers to spoof arbitrary network account servers, and possibly execute arbitrary code, via unspecified vectors.

authenticate_ad_setup_finished.cfm in MediaCAST 8 and earlier allows remote attackers to discover usernames and cleartext passwords by reading the error messages returned for requests that use the UserID parameter.

The configuration page in ToutVirtual VirtualIQ Pro 3.2 build 7882 contains cleartext SSH credentials, which allows remote attackers to obtain sensitive information by reading the username and password fields.

The dhost web service in Novell eDirectory 8.8.5 uses a predictable session cookie, which makes it easier for remote attackers to hijack sessions via a modified cookie.

The SSH service on the TANDBERG Video Communication Server (VCS) before X5.1 uses a fixed DSA key, which makes it easier for remote attackers to conduct man-in-the-middle attacks and spoof arbitrary servers via crafted SSH packets.

IBM WebSphere Commerce 7.0 does not properly encrypt data in a database, which makes it easier for local users to obtain sensitive information by defeating cryptographic protection mechanisms.

IBM WebSphere Commerce 7.0 uses the same cryptographic key for session attributes and merchant data encryption, which has unspecified impact and remote attack vectors.

openssl: NETSCAPE_REUSE_CIPHER_CHANGE_BUG downgrade-to-disabled ciphersuite attack

OpenSSL before 0.9.8j, when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is enabled, does not prevent modification of the ciphersuite in the session cache, which allows remote attackers to force the use of a disabled cipher via vectors involving sniffing network traffic to discover a session identifier, a different vulnerability than CVE-2010-4180.

krb5: multiple checksum handling vulnerabilities (MITKRB5-SA-2010-007)

MIT Kerberos 5 (aka krb5) 1.7.x and 1.8.x through 1.8.3 does not properly determine the acceptability of checksums, which might allow remote attackers to forge GSS tokens, gain privileges, or have unspecified other impact via (1) an unkeyed checksum, (2) an unkeyed PAC checksum, or (3) a KrbFastArmoredReq checksum based on an RC4 key.

krb5: incorrect acceptance of certain checksums (MITKRB5-SA-2010-007)

MIT Kerberos 5 (aka krb5) 1.3.x, 1.4.x, 1.5.x, 1.6.x, 1.7.x, and 1.8.x through 1.8.3 does not properly determine the acceptability of checksums, which might allow remote attackers to modify user-visible prompt text, modify a response to a Key Distribution Center (KDC), or forge a KRB-SAFE message via certain checksums that (1) are unkeyed or (2) use RC4 keys.

openssl: invalid ASN1 module definition for CMS

The Cryptographic Message Syntax (CMS) implementation in crypto/cms/cms_asn1.c in OpenSSL before 0.9.8o and 1.x before 1.0.0a does not properly handle structures that contain OriginatorInfo, which allows context-dependent attackers to modify invalid memory locations or conduct double-free attacks, and possibly execute arbitrary code, via unspecified vectors.

Microsoft Dynamics GP uses a substitution cipher to encrypt the system password field and unspecified other fields, which makes it easier for remote authenticated users to obtain sensitive information by decrypting a field's contents.

The site-locking implementation in the SdcWebSecureBase interface in tgctlcm.dll in Consona Live Assistance, Dynamic Agent, and Subscriber Assistance relies on a list of server domain names to restrict execution of ActiveX controls, which makes it easier for man-in-the-middle attackers to execute arbitrary code via a DNS hijacking attack.

tgsrv.exe in the Repair Service in Consona Dynamic Agent, Repair Manager, Subscriber Activation, and Subscriber Agent relies on a predictable timestamp field to validate input to the \\.\pipe\__RepairService_pipe__company named pipe, which allows remote authenticated users to execute arbitrary code by obtaining the current time from (1) tcpip.sys or (2) an SMB2 service.

gnutls: unknown hash algorithm NULL pointer derefence [GNUTLS-SA-2006-2]

The _gnutls_x509_oid2mac_algorithm function in lib/gnutls_algorithms.c in GnuTLS before 1.4.2 allows remote attackers to cause a denial of service (crash) via a crafted X.509 certificate that uses a hash algorithm that is not supported by GnuTLS, which triggers a NULL pointer dereference.

The Diffie-Hellman key-exchange implementation in dhm.c in PolarSSL before 0.14.2 does not properly validate a public parameter, which makes it easier for man-in-the-middle attackers to obtain the shared secret key by modifying network traffic, a related issue to CVE-2011-5095.

openssl: ECDSA private key leak through a remote timing attack

The elliptic curve cryptography (ECC) subsystem in OpenSSL 1.0.0d and earlier, when the Elliptic Curve Digital Signature Algorithm (ECDSA) is used for the ECDHE_ECDSA cipher suite, does not properly implement curves over binary fields, which makes it easier for context-dependent attackers to determine private keys via a timing attack and a lattice calculation.

ruby: Properly initialize the random number generator when forking new process

Ruby before 1.8.7-p352 does not reset the random seed upon forking, which makes it easier for context-dependent attackers to predict the values of random numbers by leveraging knowledge of the number sequence obtained in a different child process, a related issue to CVE-2003-0900. NOTE: this issue exists because of a regression during Ruby 1.8.6 development.
