CVSS: 7.5EPSS: 1%CPEs: 1EXPL: 0CVE-2017-6004 – pcre: Out-of-bounds read in compile_bracket_matchingpath function (8.41/3)
https://notcve.org/view.php?id=CVE-2017-6004
The compile_bracket_matchingpath function in pcre_jit_compile.c in PCRE through 8.x before revision 1680 (e.g., the PHP 7.1.1 bundled version) allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted regular expression. La función compile_bracket_matchingpath en pcre_jit_compile.c en PCRE hasta la versión 8.x en versiones anteriores a la revisión 1680 (por ejemplo, la versión empacada de PHP 7.1.1) permite a atacantes remotos provocar una denegación de servicio (lectura fuera de límites y caída de la aplicación) a través de una expresión regular manipulada. • http://www.securityfocus.com/bid/96295 http://www.securitytracker.com/id/1037850 https://access.redhat.com/errata/RHSA-2018:2486 https://bugs.exim.org/show_bug.cgi?id=2035 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://security.gentoo.org/glsa/201706-11 https://vcs.pcre.org/pcre/code/trunk/pcre_ji • CWE-125: Out-of-bounds Read •

CVSS: 9.8EPSS: 15%CPEs: 19EXPL: 1CVE-2016-3191 – PCRE Regular Expression Compilation Stack Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=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. La función compile_branch en pcre_compile.c en PCRE 8.x en versiones anteriores a 8.39 y pcre2_compile.c en PCRE2 en versiones anteriores a 10.22 no maneja correctamente patrones que contienen una subcadena (*ACCEPT) en conjunción con paréntesis anidados, lo que permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (desbordamiento de buffer basado en pila) a través de una expresión regular manipuada, según lo demostrado por un objeto JavaScript RegExp encontrado por Konqueror, también conocido como ZDI-CAN-3542. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of PCRE. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the compilation of regular expressions. The issue lies in the failure to validate that compilation of sub-groups will occur within the bounds of a fixed-size stack buffer. • http://rhn.redhat.com/errata/RHSA-2016-1025.html http://vcs.pcre.org/pcre2?view=revision&revision=489 http://vcs.pcre.org/pcre?view=revision&revision=1631 http://www-01.ibm.com/support/docview.wss?uid=isg3T1023886 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securityfocus.com/bid/84810 https://access.redhat.com/errata/RHSA-2016:1132 https://bto.bluecoat.com/security-advisory/sa128 https://bugs.debian.org/815920 https://bugs.debia • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •
