Security Fix(es) :

  - Multiple flaws were found in the way PCRE handled     malformed regular expressions. An attacker able to make     an application using PCRE process a specially crafted     regular expression could use these flaws to cause the     application to crash or, possibly, execute arbitrary     code. (CVE-2015-8385, CVE-2016-3191, CVE-2015-2328,     CVE-2015-3217, CVE-2015-5073, CVE-2015-8388,     CVE-2015-8391, CVE-2015-8386)

This update for pcre to version 8.39 (bsc#972127) fixes several issues.

If you use pcre extensively please be aware that this is an update to a new version. Please make sure that your software works with the updated version.

This version fixes a number of vulnerabilities that affect pcre and applications using the libary when accepting untrusted input as regular expressions or as part thereof. Remote attackers could have caused the application to crash, disclose information or potentially execute arbitrary code. These security issues were fixed :

  - CVE-2014-8964: Heap-based buffer overflow in PCRE     allowed remote attackers to cause a denial of service     (crash) or have other unspecified impact via a crafted     regular expression, related to an assertion that allows     zero repeats (bsc#906574).

  - CVE-2015-2325: Heap buffer overflow in compile_branch()     (bsc#924960).

  - CVE-2015-3210: Heap buffer overflow in pcre_compile2() /     compile_regex() (bsc#933288)

  - CVE-2015-3217: PCRE Library Call Stack Overflow     Vulnerability in match() (bsc#933878).

  - CVE-2015-5073: Library Heap Overflow Vulnerability in     find_fixedlength() (bsc#936227).

  - bsc#942865: heap overflow in compile_regex()

  - CVE-2015-8380: The pcre_exec function in pcre_exec.c     mishandled a // pattern with a \01 string, which allowed     remote attackers to cause a denial of service     (heap-based buffer overflow) or possibly have     unspecified other impact via a crafted regular     expression, as demonstrated by a JavaScript RegExp     object encountered by Konqueror (bsc#957566).

  - CVE-2015-2327: PCRE mishandled certain patterns with     internal recursive back references, which allowed remote     attackers to cause a denial of service (segmentation     fault) or possibly have unspecified other impact via a     crafted regular expression, as demonstrated by a     JavaScript RegExp object encountered by Konqueror     (bsc#957567).

  - bsc#957598: Various security issues 

  - CVE-2015-8381: Heap Overflow in compile_regex()     (bsc#957598).

  - CVE-2015-8382: Regular Expression Uninitialized Pointer     Information Disclosure Vulnerability     (ZDI-CAN-2547)(bsc#957598).

  - CVE-2015-8383: Buffer overflow caused by repeated     conditional group(bsc#957598).

  - CVE-2015-8384: Buffer overflow caused by recursive back     reference by name within certain group(bsc#957598).

  - CVE-2015-8389: Infinite recursion in JIT compiler when     processing certain patterns(bsc#957598).

  - CVE-2015-8390: Reading from uninitialized memory when     processing certain patterns(bsc#957598).

  - CVE-2015-8391: Some pathological patterns causes     pcre_compile() to run for a very long time(bsc#957598).

  - CVE-2015-8392: Buffer overflow caused by certain     patterns with duplicated named groups(bsc#957598).

  - CVE-2015-8393: Information leak when running pcgrep -q     on crafted binary(bsc#957598).

  - CVE-2015-8394: Integer overflow caused by missing check     for certain conditions(bsc#957598).

  - CVE-2015-8395: Buffer overflow caused by certain     references(bsc#957598).

  - CVE-2015-2328: PCRE mishandled the /((?(R)a|(?1)))+/     pattern and related patterns with certain recursion,     which allowed remote attackers to cause a denial of     service (segmentation fault) or possibly have     unspecified other impact via a crafted regular     expression (bsc#957600).

  - CVE-2016-1283: The pcre_compile2 function in     pcre_compile.c in PCRE mishandled certain patterns with     named subgroups, which allowed remote attackers to cause     a denial of service (heap-based buffer overflow) or     possibly have unspecified other impact via a crafted     regular expression (bsc#960837).

  - CVE-2016-3191: The compile_branch function in     pcre_compile.c in pcre2_compile.c mishandled patterns     containing an (*ACCEPT) substring in conjunction with     nested parentheses, which allowed remote attackers to     execute arbitrary code or cause a denial of service     (stack-based buffer overflow) via a crafted regular     expression (bsc#971741).

These non-security issues were fixed :

  - JIT compiler improvements

  - performance improvements

  - The Unicode data tables have been updated to Unicode     7.0.0.

This update was imported from the SUSE:SLE-12:Update update project.

Philip Hazel reports :

PCRE does not validate that handling the (*ACCEPT) verb will occur within the bounds of the cworkspace stack buffer, leading to a stack buffer overflow.

    Oracle MySQL 5.5.48 and earlier, 5.6.29 and earlier, and 5.7.11 and     earlier; and Percona Server do not properly verify that the server     hostname matches a domain name in the subject's Common Name (CN) or     subjectAltName field of the X.509 certificate, which allows     man-in-the-middle attackers to spoof SSL servers via a /CN= string     in a field in a certificate, as demonstrated by     /OU=/CN=bar.com/CN=foo.com.
    CVE-2016-3191     The compile_branch function in pcre_compile.c in PCRE 8.x before 8.39     and pcre2_compile.c in PCRE2 before 10.22 mishandles patterns     containing an (*ACCEPT) substring in conjunction with nested     parentheses, which allows remote attackers to execute arbitrary code     or cause a denial of service (stack-based buffer overflow) via a     crafted regular expression, as demonstrated by a JavaScript RegExp     object encountered by Konqueror, aka ZDI-CAN-3542.

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:1132 advisory.

    MariaDB is a multi-user, multi-threaded SQL database server. For all practical purposes, MariaDB is     binary-compatible with MySQL. MariaDB uses PCRE, a Perl-compatible regular expression library, to     implement regular expression support in SQL queries.

    Security Fix(es):

    * It was found that the MariaDB client library did not properly check host names against server identities     noted in the X.509 certificates when establishing secure connections using TLS/SSL. A man-in-the-middle     attacker could possibly use this flaw to impersonate a server to a client. (CVE-2016-2047)

    * This update fixes several vulnerabilities in the MariaDB database server. Information about these flaws     can be found on the Oracle Critical Patch Update Advisory page, listed in the References section.
    (CVE-2015-4792, CVE-2015-4802, CVE-2015-4815, CVE-2015-4816, CVE-2015-4819, CVE-2015-4826, CVE-2015-4830,     CVE-2015-4836, CVE-2015-4858, CVE-2015-4861, CVE-2015-4870, CVE-2015-4879, CVE-2015-4895, CVE-2015-4913,     CVE-2016-0505, CVE-2016-0546, CVE-2016-0596, CVE-2016-0597, CVE-2016-0598, CVE-2016-0600, CVE-2016-0606,     CVE-2016-0608, CVE-2016-0609, CVE-2016-0610, CVE-2016-0616, CVE-2016-0640, CVE-2016-0641, CVE-2016-0642,     CVE-2016-0643, CVE-2016-0644, CVE-2016-0646, CVE-2016-0647, CVE-2016-0648, CVE-2016-0649, CVE-2016-0650,     CVE-2016-0651, CVE-2016-0655, CVE-2016-0666, CVE-2016-0668)

    * Multiple flaws were found in the way PCRE handled malformed regular expressions. An attacker able to     make MariaDB execute an SQL query with a specially crafted regular expression could use these flaws to     cause it to crash or, possibly, execute arbitrary code. (CVE-2015-3210, CVE-2015-3217, CVE-2015-5073,     CVE-2015-8381, CVE-2015-8383, CVE-2015-8384, CVE-2015-8385, CVE-2015-8386, CVE-2015-8388, CVE-2015-8391,     CVE-2015-8392, CVE-2015-8395, CVE-2016-1283, CVE-2016-3191)

  - PCRE before 8.38 mishandles the interaction of     lookbehind assertions and mutually recursive     subpatterns, which allows remote attackers to cause a     denial of service (buffer overflow) or possibly have     unspecified other impact via a crafted regular     expression, as demonstrated by a JavaScript RegExp     object encountered by Konqueror.(CVE-2015-8386)

  - PCRE 7.8 and 8.32 through 8.37, and PCRE2 10.10     mishandle group empty matches, which might allow remote     attackers to cause a denial of service (stack-based     buffer overflow) via a crafted regular expression, as     demonstrated by     /^(?:(?(1)\\\\.|(^\\\\\\\\W_)?)+)+$/.(CVE-2015-3217)
