CVE-2009-1955 – Apache mod_dav / svn - Remote Denial of Service
https://notcve.org/view.php?id=CVE-2009-1955
The expat XML parser in the apr_xml_* interface in xml/apr_xml.c in Apache APR-util before 1.3.7, as used in the mod_dav and mod_dav_svn modules in the Apache HTTP Server, allows remote attackers to cause a denial of service (memory consumption) via a crafted XML document containing a large number of nested entity references, as demonstrated by a PROPFIND request, a similar issue to CVE-2003-1564. El parseador XML en el interfaz apr_xml_* en xml/apr_xml.c en Apache APR-util anteriores a v1.3.7 tal y como es utilizado en los módulos mod_dav y mod_dav_svn en el servidor HTTP de Apache, permite a atacantes remotos producir una denegación de servicio (agotamiento de memoria) a través de un documento XML manipulado que contiene un gran numero de referencias anidadas, como se demostró en la petición PROPFIND, una vulnerabilidad similar a CVE-2003-1564. • https://www.exploit-db.com/exploits/8842 http://lists.apple.com/archives/security-announce/2009/Nov/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2010-05/msg00001.html http://marc.info/?l=apr-dev&m=124396021826125&w=2 http://marc.info/?l=bugtraq&m=129190899612998&w=2 http://secunia.com/advisories/34724 http://secunia.com/advisories/35284 http://secunia.com/advisories/35360 http://secunia.com/advisories/35395 http://secunia.com/advisories/35444 http: • CWE-776: Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion') •
CVE-2009-0949 – CUPS 1.3.9 - 'cups/ipp.c' Null Pointer Dereference Denial of Service
https://notcve.org/view.php?id=CVE-2009-0949
The ippReadIO function in cups/ipp.c in cupsd in CUPS before 1.3.10 does not properly initialize memory for IPP request packets, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a scheduler request with two consecutive IPP_TAG_UNSUPPORTED tags. La función ippReadIO en cups/ipp.c en cupsd en CUPS antes de la versión 1.3.10 no inicia de manera apropiada la memoria para paquetes de solicitud IPP, lo que permite a atacantes remotos provocar una denegación de servicio (referencia a puntero nulo y caída del demonio) mediante una solicitud de programación (scheduler) con dos etiquetas IPP_TAG_UNSUPPORTED consecutivas. • https://www.exploit-db.com/exploits/33020 http://lists.apple.com/archives/security-announce/2009/Sep/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2009-07/msg00002.html http://secunia.com/advisories/35322 http://secunia.com/advisories/35328 http://secunia.com/advisories/35340 http://secunia.com/advisories/35342 http://secunia.com/advisories/35685 http://secunia.com/advisories/36701 http://securitytracker.com/id?1022321 http://support.apple.com/kb/HT3865 http • CWE-476: NULL Pointer Dereference CWE-908: Use of Uninitialized Resource •
CVE-2009-0846 – krb5: ASN.1 decoder can free uninitialized pointer when decoding an invalid encoding (MITKRB5-SA-2009-002)
https://notcve.org/view.php?id=CVE-2009-0846
The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.c in the ASN.1 GeneralizedTime decoder in MIT Kerberos 5 (aka krb5) before 1.6.4 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via vectors involving an invalid DER encoding that triggers a free of an uninitialized pointer. La función asn1_decode_generaltime en lib/krb5/asn.1/asn1_decode.c en el decodificador ASN.1 GeneralizedTime en MIT Kerberos 5 (también conocido como Krb5) anteriores a v1.6.4, permite a atacantes remotos provocar una denegación de servicio (caída del demonio) o posiblemente ejecución de código de su elección a través de vectores que implican una codificación DER inválida, que provocará una liberación del puntero no inicializado. • http://lists.apple.com/archives/security-announce/2009/May/msg00002.html http://lists.vmware.com/pipermail/security-announce/2009/000059.html http://marc.info/?l=bugtraq&m=124896429301168&w=2 http://marc.info/?l=bugtraq&m=130497213107107&w=2 http://rhn.redhat.com/errata/RHSA-2009-0409.html http://rhn.redhat.com/errata/RHSA-2009-0410.html http://secunia.com/advisories/34594 http://secunia.com/advisories/34598 http://secunia.com/advisories/34617 http://secunia.com/adv • CWE-416: Use After Free CWE-824: Access of Uninitialized Pointer •
CVE-2009-1238 – Apple Mac OSX xnu 1228.x - 'vfssysctl' Local Kernel Denial of Service (PoC)
https://notcve.org/view.php?id=CVE-2009-1238
Race condition in the HFS vfs sysctl interface in XNU 1228.8.20 and earlier on Apple Mac OS X 10.5.6 and earlier allows local users to cause a denial of service (kernel memory corruption) by simultaneously executing the same HFS_SET_PKG_EXTENSIONS code path in multiple threads, which is problematic because of lack of mutex locking for an unspecified global variable. Condición de carrera en el interfaz HFS vfs sysctl en XNU v1228.8.20 y anteriores en Apple Mac OS X v10.5.6 y anteriores permite a usuarios locales producir una denegación de servicio (corrupción de la memoria del kernel) mediante la ejecucion simultanea de la ruta de código HFS_SET_PKG_EXTENSIONS en múltiples lineas de ejecución, lo cual es problemático debido a la ausencia de bloqueo de mutex para una variable inespecífica global. • https://www.exploit-db.com/exploits/8265 http://secunia.com/advisories/34424 http://www.digit-labs.org/files/exploits/xnu-vfssysctl-dos.c http://www.informationweek.com/news/hardware/mac/showArticle.jhtml?articleID=216401181 http://www.securityfocus.com/bid/34202 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

Heap-based buffer overflow in the AppleTalk networking stack in XNU 1228.3.13 and earlier on Apple Mac OS X 10.5.6 and earlier allows remote attackers to cause a denial of service (system crash) via a ZIP NOTIFY (aka ZIPOP_NOTIFY) packet that overwrites a certain ifPort structure member. Desbordamiento de búfer basado en pila en AppleTalk networking stack en XNU v1228.3.13 y anteriores en Apple Mac OS X v10.5.6 permite a atacantes remotos producir una denegación de servicio (caída del sistema) a través de un paquete NOTIFY (también conocido como ZIPOP_NOTIFY) que sobrescribe miembro de estructura ifPort. • https://www.exploit-db.com/exploits/8262 http://secunia.com/advisories/34424 http://www.digit-labs.org/files/exploits/xnu-appletalk-zip.c http://www.informationweek.com/news/hardware/mac/showArticle.jhtml?articleID=216401181 http://www.securityfocus.com/bid/34201 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
