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.
Severity: 2/4.
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.
Full Vigil@nce bulletin... (Free trial)
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.
Severity: 2/4.
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.

Henry Spencer regex, PHP, MySQL: buffer overflow of regcomp
Synthesis of the vulnerability
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.
Severity: 2/4.

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 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.

glibc: unreachable memory reading via fnmatch
Synthesis of the vulnerability
An attacker can force a read at an invalid address in fnmatch() of the glibc, in order to trigger a denial of service.
Severity: 1/4.
Creation date: 26/02/2015.
Identifiers: 18032, CVE-2015-8984, K29241247, STORM-2015-09-EN, STORM-2015-10-EN, STORM-2015-11-EN.2, STORM-2015-12-EN, USN-3239-1, USN-3239-2, USN-3239-3, VIGILANCE-VUL-16275.

Description of the vulnerability
The fnmatch() function of the glibc checks if a string matches a pattern:
fnmatch(pattern, string, flags);
For example:
if (fnmatch("*.txt", "file.txt", 0)) ...
However, if the pattern contains an unclosed '[', the internal_fnmatch() function tries to read a memory area which is not reachable, which triggers a fatal error.
An attacker can therefore force a read at an invalid address in fnmatch() of the glibc, in order to trigger a denial of service.

glibc: buffer overflow of scanf
Synthesis of the vulnerability
An attacker can generate a buffer overflow in scanf() functions of the glibc, in order to trigger a denial of service, and possibly to execute code.
Severity: 2/4.
Creation date: 26/02/2015.
Identifiers: 13138, CVE-2011-5320, STORM-2015-09-EN, STORM-2015-10-EN, STORM-2015-11-EN.2, STORM-2015-12-EN, VIGILANCE-VUL-16271.

Description of the vulnerability
Functions in the scanf() family analyze a string to store it in variables. For example, to decode an integer:
scanf("%i", &integer);
However, if the size of data is greater than the size of the storage array, an overflow occurs in the _IO_vfscanf_internal() function.
An attacker can therefore generate a buffer overflow in scanf() functions of the glibc, in order to trigger a denial of service, and possibly to execute code.

glibc: denial of service via swscanf
Synthesis of the vulnerability
An attacker can consume too many memory in the swscanf() function of the glibc, in order to trigger a denial of service.
Severity: 1/4.
Creation date: 04/02/2015.
Identifiers: 16618, CVE-2015-1473, DSA-3169-1, MDVSA-2015:168, RHSA-2015:2199-07, RHSA-2015:2589-01, STORM-2015-09-EN, STORM-2015-10-EN, STORM-2015-11-EN.2, STORM-2015-12-EN, USN-2519-1, VIGILANCE-VUL-16106.
Full Vigil@nce bulletin... (Free trial)
Description of the vulnerability
The swscanf() function of the glibc searches for a pattern in a wide-character string.
Before reserving a stack memory area via alloca(), the swscanf() function calls __libc_use_alloca() which checks if the requested size is inferior to the limit __MAX_ALLOCA_CUTOFF. However, a number of characters is compared instead of a number of bytes. The alloca() function can thus be used up to 4 times the expected limit, which may stop the application.
An attacker can therefore consume too many memory in the swscanf() function of the glibc, in order to trigger a denial of service.
