Description of the vulnerability
Several vulnerabilities were announced in OpenSSL.
An attacker can act as a Man-in-the-Middle on a server supporting SSLv2 and EXPORT ciphers (this configuration is considered as weak since several years), in order to read or write data in the session. [severity:2/4; CVE-2016-0800, VU#583776]
An attacker can force the usage of a freed memory area when OpenSSL processes a DSA private key (this scenario is rare), in order to trigger a denial of service, and possibly to run code. [severity:2/4; CVE-2016-0705]
An attacker can read a memory fragment via SRP_VBASE_get_by_user, in order to obtain sensitive information. [severity:1/4; CVE-2016-0798]
An attacker can force a NULL pointer to be dereferenced in BN_hex2bn(), in order to trigger a denial of service. [severity:1/4; CVE-2016-0797]
An attacker can use a very large string (size INT_MAX), to generate a memory corruption in the BIO_*printf() functions, in order to trigger a denial of service, and possibly to run code. [severity:2/4; CVE-2016-0799]
An attacker can use cache conflicts on Intel Sandy-Bridge, in order to obtain RSA keys. [severity:1/4; CVE-2016-0702]
An attacker can use a very large string (size INT_MAX), to generate a memory corruption in the internal doapr_outch() function, in order to trigger a denial of service, and possibly to run code. [severity:2/4; CVE-2016-2842]

The 2_srvr.c file overwrite some byte dur the Bleichenbacher protection, so an attacker can act as a Man-in-the-Middle on SSLv2, in order to read or write data in the session. [severity:2/4; CVE-2016-0704]

Description of the vulnerability
The glibc library implements a DNS resolver (libresolv).
An application can thus call the getaddrinfo() function, which queries DNS servers. When the AF_UNSPEC type is used in the getaddrinfo() call, two DNS A and AAAA queries are sent simultaneously. However, this special case, and a case with AF_INET6 are not correctly managed, and lead to an overflow if the reply coming from the DNS server is larger than 2048 bytes.
An attacker, who owns a malicious DNS server, can therefore reply with large data to a client application using the getaddrinfo() function of the glibc, in order to trigger a denial of service, and possibly to run code in the client application.

Description of the vulnerability
The OpenSSL library disables by default SSLv2, excepted if the SSL_OP_NO_SSLv2 option is used.
SSLv2 cipher algorithms can be disabled on the server. However, a malicious client can still use these algorithms.
An attacker can therefore connect to a SSLv2 server with disabled ciphers in OpenSSL, in order to create a TLS session which is not secure.

Description of the vulnerability
Since version 1.0.2, the OpenSSL library can generate DH unsafe parameters of style X9.42 (subgroup size "q"), to support the RFC 5114.
In this case, an attacker can find the private DH exponent of the peer, if the DH key is reused. The DH key is reused in the following cases:
- SSL_CTX_set_tmp_dh() or SSL_set_tmp_dh() is used without the option SSL_OP_SINGLE_DH_USE set, which is rare.
- SSL_CTX_set_tmp_dh_callback() or SSL_set_tmp_dh_callback() is used in an undocumented mode.
- Static DH ciphersuites are used.
In some special configurations, an attacker can therefore find the private DH exponent of the OpenSSL peer, in order to decrypt other sessions.

cURL: privilege escalation via the use of proxy using NTLM authentication
Synthesis of the vulnerability
An attacker can use cURL with an HTTP proxy and NTLM authentication with the proxy account of another user, in order to escalate his privileges.
Impacted products: OpenOffice, Mac OS X, Brocade Network Advisor, Brocade vTM, curl, Debian, Fedora, Juniper EX-Series, Junos OS, SRX-Series, openSUSE, openSUSE Leap, Solaris, Slackware, Ubuntu.

Description of the vulnerability
The cURL product includes an embedable HTTP client. It can use HTTP proxies.
When a proxy requires an NTLM authentication, this authentication is connection based (in contrast to HTTP based authentication which is request based). Typically, cURL reuses TCP connections to the proxy for several HTTP requests. However, cURL may do so even if different credentials for the proxy have been specified at request level.
An attacker can therefore use cURL with an HTTP proxy and NTLM authentication with the proxy account of another user, in order to escalate his privileges.

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.
Consequences: administrator access/rights, privileged access/rights, denial of service on server.
Provenance: user shell.
Confidence: confirmed by the editor (5/5).
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.
