Linux kernel: use after free via join_session_keyring
Synthesis of the vulnerability
An attacker can force the usage of a freed memory area via the join_session_keyring() function of the Linux kernel, in order to trigger a denial of service, and possibly to run code.
Impacted products: Blue Coat CAS, Brocade Network Advisor, Brocade vTM, Debian, Fedora, Linux, openSUSE, openSUSE Leap, RHEL, SUSE Linux Enterprise Desktop, SLES, Synology DS***, Synology RS***, Ubuntu, WindRiver Linux.
Severity: 2/4.
Creation date: 19/01/2016.
Identifiers: BSA-2016-004, CVE-2016-0728, CVE-2016-7028-REJECT, DSA-3448-1, FEDORA-2016-26e19f042a, FEDORA-2016-5d43766e33, FEDORA-2016-b59fd603be, openSUSE-SU-2016:0280-1, openSUSE-SU-2016:0301-1, openSUSE-SU-2016:0318-1, RHSA-2016:0064-01, RHSA-2016:0065-01, RHSA-2016:0068-01, RHSA-2016:0103-01, SA112, SUSE-SU-2016:0186-1, SUSE-SU-2016:0205-1, USN-2870-1, USN-2870-2, USN-2871-1, USN-2871-2, USN-2872-1, USN-2872-2, USN-2872-3, USN-2873-1, VIGILANCE-VUL-18749.
Description of the vulnerability
The Linux kernel can store cryptographic keys, which are managed using keyctl.
However, if the join_session_keyring() function is used on a keyring currently in usage, a counter is not updated. This counter can then overflow, and force the object to be freed, but it is still used later.
An attacker can therefore force the usage of a freed memory area via the join_session_keyring() function of the Linux kernel, in order to trigger a denial of service, and possibly to run code.

Description of the vulnerability
The OpenSSH product implements a SSH client and server.
The SSH client contains an undocumented experimental feature named Roaming, which is implemented in the roaming_client.c file. This feature is enabled by default, and it is used to restart an old session. It is impacted by two vulnerabilities.
The Roaming feature can be used by a SSH server to read the SSH client memory, to obtain its keys. [severity:3/4; CVE-2016-0777]
The Roaming feature can be used by a SSH server to trigger an overflow and a descriptor leak in the SSH client, in order to generate a denial of service. [severity:2/4; CVE-2016-0778]
An attacker, who owns a malicious SSH server, can therefore invite a client to connect with OpenSSH, and then call the Roaming feature, in order to obtain sensitive information about keys used by the SSH client.

Description of the vulnerability
The OpenSSL library can be used by a multi-threaded client.
However, in this case, the SSL_CTX structure does not contain an updated PSK Identify Hint. OpenSSL can thus free twice the same memory area.
An attacker can therefore force the usage of a freed memory area via PSK Identify Hint of an OpenSSL multi-threaded client, in order to trigger a denial of service, and possibly to run code.

Description of the vulnerability
The OpenSSL library supports the PKCS#7 and CMS formats.
However, if an X509_ATTRIBUTE structure is malformed, OpenSSL does not initialize a memory area before returning it to the user reading PKCS#7 or CMS data.
It can be noted that SSL/TLS is not impacted.
An attacker can therefore read a memory fragment via X509_ATTRIBUTE of OpenSSL processing PKCS#7 or CMS data, in order to obtain sensitive information.

Description of the vulnerability
The OpenSSL library can use the RSA PSS algorithm to check the validity of X.509 certificates.
However, if the "mask generation" parameter is missing during the verification of a signature in ASN.1 format, OpenSSL does not check if a pointer is NULL, before using it.
An attacker can therefore force a NULL pointer to be dereferenced during the certificate verification of OpenSSL (in client or server mode), in order to trigger a denial of service.

Description of the vulnerability
The OpenSSL library uses the BN_mod_exp() function to perform a modular exponentiation on large numbers.
However, on an x86_64 processor, the BN_mod_exp() function can generate an incorrect result during the Montgomery Squaring procedure.
An attacker, with a significant amount of resources, can therefore attack the DH algorithm, in some OpenSSL usages, in order to compute the private key.

Description of the vulnerability
The Apache Commons Collections library is used by several Java applications.
A Java Gadgets ("gadget chains") object can contain Transformers, with an "exec" string containing a shell command which is run with the Java.lang.Runtime.exec() method. When raw data are unserialized, the readObject() method is thus called to rebuild the Gadgets object, and it uses InvokerTransformer, which runs the indicated shell command.
It can be noted that other classes (CloneTransformer, ForClosure, InstantiateFactory, InstantiateTransformer, PrototypeCloneFactory, PrototypeSerializationFactory, WhileClosure) also execute a shell command from raw data to deserialize.
However, several applications publicly expose (before authentication) the Java unserialization feature.
An attacker can therefore send a malicious serialized Gadget Chain object to a Java application using Apache Commons Collections, in order to run shell code.

GNU GCC: predictability of std-random_device
Synthesis of the vulnerability
An attacker can predict some randoms generated by C++ programs compiled with GNU GCC.
Impacted products: FabricOS, Brocade Network Advisor, Brocade vTM, GCC, openSUSE Leap, SUSE Linux Enterprise Desktop, SLES.
Severity: 2/4.
Creation date: 10/11/2015.
Identifiers: BSA-2016-006, CVE-2015-5276, openSUSE-SU-2015:1946-1, openSUSE-SU-2016:1069-1, SUSE-SU-2017:2235-1, VIGILANCE-VUL-18272.
Description of the vulnerability
The GNU GCC product contains the libstdc++ library, which implements the std::random_device class.
The std::random_device::_M_getval() method of libstdc++ is used to generate random numbers from a file. However, it does not check the return value of the read() function. If an error occurs (blocked file), random data are thus initialized from the stack content.
An attacker can therefore predict some randoms generated by C++ programs compiled with GNU GCC.
