Dnsmasq: information disclosure via tcp_request
Synthesis of the vulnerability
A local attacker can read a memory fragment of Dnsmasq, in order to obtain sensitive information; and maybe make the server halt.
Impacted products: Arkoon FAST360, Debian, Dnsmasq, openSUSE, Solaris, SUSE Linux Enterprise Desktop, SLES, Ubuntu.
Severity: 2/4.
Consequences: data reading, denial of service on service.
Provenance: internet client.
Creation date: 17/04/2015.
Identifiers: bulletinjul2015, CVE-2015-3294, DSA-3251-1, DSA-3251-2, openSUSE-SU-2015:0857-1, OSI-1502, STORM-2015-09-EN, STORM-2015-10-EN, STORM-2015-11-EN.2, STORM-2015-12-EN, SUSE-SU-2017:2616-1, SUSE-SU-2017:2617-1, SUSE-SU-2017:2619-1, USN-2593-1, VIGILANCE-VUL-16649.
Description of the vulnerability
The Dnsmasq includes a DNS cache.
The routine tcp_request() builds the response packet. However, the function "setup_reply" does not take into account some possible errors while evaluating the response size. Such an error would make the server return uninitialized data from the process heap and maybe reference an invalid address, and then make the server process be killed.
A local attacker can therefore read a memory fragment of Dnsmasq, in order to obtain sensitive information; and maybe make the server halt.

Net-SNMP: memory leak via snmp_pdu_parse
Synthesis of the vulnerability
An attacker can create a memory leak in snmp_pdu_parse() of Net-SNMP, in order to trigger a denial of service.
Impacted products: Arkoon FAST360, XenServer, Debian, BIG-IP Hardware, TMOS, MBS, Net-SNMP, openSUSE, Solaris, RHEL, Ubuntu.
Severity: 2/4.
Consequences: denial of service on server, denial of service on service, denial of service on client.
Provenance: intranet client.
Creation date: 13/04/2015.
Identifiers: bulletinoct2016, CERTFR-2016-AVI-133, CTX209443, CVE-2015-5621, DSA-4154-1, MDVSA-2015:229, openSUSE-SU-2015:1502-1, RHSA-2015:1636-01, SOL17378, STORM-2015-09-EN, STORM-2015-10-EN, STORM-2015-11-EN.2, STORM-2015-12-EN, USN-2711-1, VIGILANCE-VUL-16576.
Description of the vulnerability
The Net-SNMP product uses the snmp_pdu_parse() function to analyze data of SNMP packets.
However, after an error, the memory allocated to process an option in snmp_parse_var_op() is never freed.
An attacker can therefore create a memory leak in snmp_pdu_parse() of Net-SNMP, in order to trigger a denial of service.

An attacker can generate a buffer overflow in the regcomp() function of Henry Spencer regex, in order to trigger a denial of service, and possibly to execute code.
Impacted products: Arkoon FAST360, Debian, Fedora, HP-UX, MySQL Community, MySQL Enterprise, openSUSE, Percona Server, XtraDB Cluster, PHP, RHEL, Slackware, SUSE Linux Enterprise Desktop, SLES, Ubuntu, Unix (platform) ~ not comprehensive.
Severity: 2/4.
Consequences: user access/rights, denial of service on service, denial of service on client.
Provenance: document.

Description of the vulnerability
The Henry Spencer regex library implements the support of regular expressions. It is used by PHP and MySQL.
The regcomp() function generates a data structure representing a regular expression.
However, if the size of data is greater than the size of the storage array, an overflow occurs in regcomp().
An attacker can therefore generate a buffer overflow in the regcomp() function of Henry Spencer regex, in order to trigger a denial of service, and possibly to execute code.

Description of the vulnerability
The OpenSSL product processes X.509 certificates.
However, the X509_to_X509_REQ() function does not check if a pointer is NULL, before using it.
An attacker can therefore force a NULL pointer to be dereferenced in X509_to_X509_REQ() of OpenSSL, in order to trigger a denial of service.

Description of the vulnerability
The TLS protocol uses a series of messages which have to be exchanged between the client and the server, before establishing a secured session.
Several cryptographic algorithms can be negotiated, such as algorithms allowed for USA export (less than 512 bits).
An attacker, located as a Man-in-the-Middle, can inject during the session initialization a message choosing an export algorithm. This message should generate an error, however some TLS clients accept it.
Note: the variant related to Windows is described in VIGILANCE-VUL-16332.
An attacker, located as a Man-in-the-Middle, can therefore force the Chrome, JSSE, LibReSSL, Mono or OpenSSL client to accept a weak export algorithm, in order to more easily capture or alter exchanged data.
