Poul-Henning Kamp md5crypt has insufficient algorithmic complexity and a consequently short runtime, which makes it easier for context-dependent attackers to discover cleartext passwords via a brute-force attack, as demonstrated by an attack using GPU hardware.

The datasource definition editor in IBM InfoSphere Guardium 8.2 and earlier, when the save-password setting is enabled, transmits cleartext database credentials, which allows remote attackers to obtain sensitive information by sniffing the network.

System: CA certificate can be revoked

Red Hat Certificate System (RHCS) before 8.1.1 and Dogtag Certificate System does not properly check certificate revocation requests made through the web interface, which allows remote attackers with permissions to revoke end entity certificates to revoke the Certificate Authority (CA) certificate.

The default configuration of Cyberoam UTM appliances uses the same Certification Authority certificate and same private key across different customers' installations, which makes it easier for man-in-the-middle attackers to spoof SSL servers by leveraging the presence of the Cyberoam_SSL_CA certificate in a list of trusted root certification authorities. NOTE: the vendor disputes the significance of this issue because the appliance "does not allow import or export of the foresaid private key.

DataNodes in Apache Hadoop 2.0.0 alpha does not check the BlockTokens of clients when Kerberos is enabled and the DataNode has checked out the same BlockPool twice from a NodeName, which might allow remote clients to read arbitrary blocks, write to blocks to which they only have read access, and have other unspecified impacts.

The register_application function in atk-adaptor/bridge.c in GNOME at-spi2-atk 2.5.2 does not seed the random number generator and generates predictable temporary file names, which makes it easier for local users to create or truncate files via a symlink attack on a temporary socket file in /tmp/at-spi2.

Teiid: JDBC socket does not encrypt client login messages by default

The Teiid Java Database Connectivity (JDBC) socket, as used in JBoss Enterprise Data Services Platform before 5.3.0, does not encrypt login messages by default contrary to documentation and specification, which allows remote attackers to obtain login credentials via a man-in-the-middle (MITM) attack.

python-beaker: weak use of crypto can leak information to remote attackers

Beaker before 1.6.4, when using PyCrypto to encrypt sessions, uses AES in ECB cipher mode, which might allow remote attackers to obtain portions of sensitive session data via unspecified vectors.

Belkin wireless routers Surf N150 Model F7D1301v1, N900 Model F9K1104v1, N450 Model F9K1105V2, and N300 Model F7D2301v1 generate a predictable default WPA2-PSK passphrase based on eight digits of the WAN MAC address, which allows remote attackers to access the network by sniffing the beacon frames.

python-keyring: weak encryption in keyring

Python Keyring 0.9.1 does not securely initialize the cipher when encrypting passwords for CryptedFileKeyring files, which makes it easier for local users to obtain passwords via a brute-force attack.

The geli encryption provider 7 before r239184 on FreeBSD 10 uses a weak Master Key, which makes it easier for local users to defeat a cryptographic protection mechanism via a brute-force attack.

McAfee Email and Web Security (EWS) 5.x before 5.5 Patch 6 and 5.6 before Patch 3, and McAfee Email Gateway (MEG) 7.0 before Patch 1, does not properly encrypt system-backup data, which makes it easier for remote authenticated users to obtain sensitive information by reading a backup file, as demonstrated by obtaining password hashes.

The default configuration of Cerberus FTP Server before 5.0.4.0 supports the DES cipher for SSH sessions, which makes it easier for remote attackers to obtain sensitive information by sniffing the network and performing a brute-force attack on the encrypted data.

jruby: Murmur hash function collisions (oCERT-2012-001)

JRuby computes hash values without properly restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table, as demonstrated by a universal multicollision attack against the MurmurHash2 algorithm, a different vulnerability than CVE-2011-4838.

ruby: Murmur hash-flooding DoS flaw in ruby 1.9 (oCERT-2012-001)

Ruby (aka CRuby) 1.9 before 1.9.3-p327 and 2.0 before r37575 computes hash values without properly restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table, as demonstrated by a universal multicollision attack against a variant of the MurmurHash2 algorithm, a different vulnerability than CVE-2011-4815.

Rubinius computes hash values without properly restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table, as demonstrated by a universal multicollision attack against the MurmurHash3 algorithm.

java: Murmur hash function collisions (oCERT-2012-001)

Oracle Java SE 7 and earlier, and OpenJDK 7 and earlier, computes hash values without properly restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table, as demonstrated by a universal multicollision attack against the MurmurHash3 algorithm, a different vulnerability than CVE-2012-2739.

(btrfs): DoS (extended runtime of kernel code) via CRC32C hash collisions

The CRC32C feature in the Btrfs implementation in the Linux kernel before 3.8-rc1 allows local users to cause a denial of service (extended runtime of kernel code) by creating many different files whose names are associated with the same CRC32C hash value.

(btrfs): DoS (prevention of file creation) by leveraging the ability to write to a directory important for the victim

The CRC32C feature in the Btrfs implementation in the Linux kernel before 3.8-rc1 allows local users to cause a denial of service (prevention of file creation) by leveraging the ability to write to a directory important to the victim, and creating a file with a crafted name that is associated with a specific CRC32C hash value.

The Zoner AntiVirus Free application for Android does not verify that the server hostname matches a domain name in the subject's Common Name (CN) field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate, as demonstrated by a server used for updating virus signature files.
