CVSS: 6.8EPSS: 4%CPEs: 3EXPL: 0CVE-2007-4768 – : pcre before 7.3 incorrect unicode in char class optimization
https://notcve.org/view.php?id=CVE-2007-4768
Heap-based buffer overflow in Perl-Compatible Regular Expression (PCRE) library before 7.3 allows context-dependent attackers to execute arbitrary code via a singleton Unicode sequence in a character class in a regex pattern, which is incorrectly optimized. Desbordamiento de búfer basado en montículo en la librería Perl-Compatible Regular Expression (PCRE) anterior a 7.3 permite a atacantes locales o remotos (dependiendo del contexto) ejecutar código de su elección mediante una secuencia de caracteres Unicode unitarios en una clase character de un patrón de expresión regular, lo cual está optimizado incorrectamente. • http://bugs.gentoo.org/show_bug.cgi?id=198976 http://docs.info.apple.com/article.html?artnum=307179 http://docs.info.apple.com/article.html?artnum=307562 http://lists.apple.com/archives/security-announce/2007/Dec/msg00002.html http://lists.apple.com/archives/security-announce/2008/Mar/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2007-12/msg00007.html http://mail.gnome.org/archives/gtk-devel-list/2007-November/msg00022.html http://secunia.com/advisories/27538 http& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Perl-Compatible Regular Expression (PCRE) library before 7.0 does not properly calculate sizes for unspecified "multiple forms of character class", which triggers a buffer overflow that allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code. La biblioteca Perl-Compatible Regular Expression (PCRE) anterior a la versión 7.0 no calcula apropiadamente los tamaños de las "multiple forms of character class" no especificadas, lo que desencadena un desbordamiento de búfer que permite a los atacantes dependiendo del contexto provocar una denegación de servicio (bloqueo) y posiblemente ejecutar código arbitrario. • http://bugs.gentoo.org/show_bug.cgi?id=198976 http://docs.info.apple.com/article.html?artnum=307179 http://docs.info.apple.com/article.html?artnum=307562 http://lists.apple.com/archives/security-announce/2007/Dec/msg00002.html http://lists.apple.com/archives/security-announce/2008/Mar/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2008-01/msg00006.html http://lists.vmware.com/pipermail/security-announce/2008/000014.html http://mail.gnome.org/archives/gtk-devel-list& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Perl-Compatible Regular Expression (PCRE) library before 7.3 does not properly compute the length of (1) a \p sequence, (2) a \P sequence, or (3) a \P{x} sequence, which allows context-dependent attackers to cause a denial of service (infinite loop or crash) or execute arbitrary code. La librería Perl-Compatible Regular Expression (PCRE) anterior a 7.3 no computa adecuadamente la longitud de (1) una secuencia \p, (2) una secuencia \P, o (3) una secuencia \P{x}, lo cual permite a atacantes dependientes de contexto provocar una denegación de servicio (bucle infinito o caída) o ejecutar código de su elección. • http://bugs.gentoo.org/show_bug.cgi?id=198976 http://docs.info.apple.com/article.html?artnum=307179 http://docs.info.apple.com/article.html?artnum=307562 http://lists.apple.com/archives/security-announce/2007/Dec/msg00002.html http://lists.apple.com/archives/security-announce/2008/Mar/msg00001.html http://mail.gnome.org/archives/gtk-devel-list/2007-November/msg00022.html http://secunia.com/advisories/27538 http://secunia.com/advisories/27543 http://secunia.com/advisories/27554 h •
