CVE-2007-5116 – perl regular expression UTF parsing errors
https://notcve.org/view.php?id=CVE-2007-5116
Buffer overflow in the polymorphic opcode support in the Regular Expression Engine (regcomp.c) in Perl 5.8 allows context-dependent attackers to execute arbitrary code by switching from byte to Unicode (UTF) characters in a regular expression. Desbordamiento de búfer en el soporte opcode polimórfico del Motor de Expresiones Regulares (regcomp.c) en Perl 5.8 permite a atacantes dependientes de contexto ejecutar código de su elección cambiando de byte a caracteres Unicode (UTF) en una expresión regular. • ftp://aix.software.ibm.com/aix/efixes/security/README http://docs.info.apple.com/article.html?artnum=307179 http://lists.apple.com/archives/security-announce/2007/Dec/msg00002.html http://lists.vmware.com/pipermail/security-announce/2008/000002.html http://marc.info/?l=bugtraq&m=120352263023774&w=2 http://secunia.com/advisories/27479 http://secunia.com/advisories/27515 http://secunia.com/advisories/27531 http://secunia.com/advisories/27546 http://secunia.com/advisories/27548 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2007-5365 – Ubuntu 6.06 - DHCPd Remote Denial of Service
https://notcve.org/view.php?id=CVE-2007-5365
Stack-based buffer overflow in the cons_options function in options.c in dhcpd in OpenBSD 4.0 through 4.2, and some other dhcpd implementations based on ISC dhcp-2, allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a DHCP request specifying a maximum message size smaller than the minimum IP MTU. Un desbordamiento de búfer en la región stack de la memoria en la función cons_options en el archivo options.c en dhcpd en OpenBSD versiones 4.0 hasta 4.2, y algunas otras implementaciones de dhcpd basadas en ISC dhcp-2, permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (bloqueo del demonio) por medio de una petición DHCP que especifica un tamaño máximo de mensaje más pequeño que el IP MTU mínimo. • https://www.exploit-db.com/exploits/4601 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=446354 http://secunia.com/advisories/27160 http://secunia.com/advisories/27273 http://secunia.com/advisories/27338 http://secunia.com/advisories/27350 http://secunia.com/advisories/32668 http://securitytracker.com/id?1021157 http://sunsolve.sun.com/search/document.do?assetkey=1-21-109077-21-1 http://sunsolve.sun.com/search/document.do?assetkey=1-26-243806-1 http://www.coresecurity • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2007-4137 – QT off by one buffer overflow
https://notcve.org/view.php?id=CVE-2007-4137
Off-by-one error in the QUtf8Decoder::toUnicode function in Trolltech Qt 3 allows context-dependent attackers to cause a denial of service (crash) via a crafted Unicode string that triggers a heap-based buffer overflow. NOTE: Qt 4 has the same error in the QUtf8Codec::convertToUnicode function, but it is not exploitable. Error de superación de límite (off-by-one) en la función QUtf8Decoder::toUnicode de Trolltech Qt3 permite a usuarios locales o remotos (dependiendo del contexto) provocar una denegación de servicio (caída) mediante una cadena Unicode manipulada que dispara un desbordamiento de búfer basado en montículo.

CVE-2007-1859 – xscreensaver authentication bypass
https://notcve.org/view.php?id=CVE-2007-1859
XScreenSaver 4.10, when using a remote directory service for credentials, does not properly handle the results from the getpwuid function in drivers/lock.c when there is no network connectivity, which causes XScreenSaver to crash and unlock the screen and allows local users to bypass authentication. XScreenSaver versión 4.10, cuando está usando un servicio de directorio remoto para credenciales, no maneja apropiadamente los resultados de la función getpwuid en el archivo drivers/lock.c cuando no hay conectividad de red, lo que causa que XScreenSaver bloquee y desbloquee la pantalla y permita a usuarios locales omitir la autenticación. • http://osvdb.org/35531 http://secunia.com/advisories/25065 http://secunia.com/advisories/25105 http://secunia.com/advisories/25116 http://secunia.com/advisories/25118 http://secunia.com/advisories/25119 http://secunia.com/advisories/25225 http://secunia.com/advisories/25610 http://security.gentoo.org/glsa/glsa-200705-14.xml http://www.mandriva.com/security/advisories?name=MDKSA-2007:097 http://www.novell.com/linux/security/advisories/2007_9_sr.html http://www.redhat • CWE-287: Improper Authentication •
