libxml2 2.6.32 and earlier does not properly detect recursion during entity expansion in an attribute value, which allows context-dependent attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document. libxml2 2.6.32 y anteriores, no detecta correctamente la recursividad durante la expansión de una entidad en un valor de un atributo; esto permite a atacantes dependientes del contexto provocar una denegación de servicio (consumo de la memoria y la CPU) mediante un documento XML manipulado. • http://lists.apple.com/archives/security-announce/2009/Jun/msg00005.html http://lists.apple.com/archives/security-announce/2009/jun/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2008-09/msg00004.html http://lists.vmware.com/pipermail/security-announce/2008/000039.html http://mail.gnome.org/archives/xml/2008-August/msg00034.html http://secunia.com/advisories/31558 http://secunia.com/advisories/31566 http://secunia.com/advisories/31590 http://secunia.com/advisories/3172 • CWE-776: Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion') •

The Linux kernel before 2.6.25.10 does not properly perform tty operations, which allows local users to cause a denial of service (system crash) or possibly gain privileges via vectors involving NULL pointer dereference of function pointers in (1) hamradio/6pack.c, (2) hamradio/mkiss.c, (3) irda/irtty-sir.c, (4) ppp_async.c, (5) ppp_synctty.c, (6) slip.c, (7) wan/x25_asy.c, and (8) wireless/strip.c in drivers/net/. El núcleo de Linux anterior a 2.6.25.10, no realiza de forma adecuada las operaciones tty, esto permite a usuarios locales provocar una denegación de servicio (caída del sistema) o posiblemente obtener privilegios mediante vectores que contienen referencias a puntero NULO en los punteros a funciones en (1) hamradio/6pack.c, (2) hamradio/mkiss.c, (3) irda/irtty-sir.c, (4) ppp_async.c, (5) ppp_synctty.c, (6) slip.c, (7) wan/x25_asy.c, y (8) wireless/strip.c en drivers/net/. • http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.25.y.git%3Ba=commitdiff%3Bh=2a739dd53ad7ee010ae6e155438507f329dce788 http://kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.25.10 http://lists.opensuse.org/opensuse-security-announce/2008-07/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2008-07/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2008-07/msg00012.html http://lists.opensuse.org/opensuse-security-announce/2008-10/msg00000.html http://l • CWE-476: NULL Pointer Dereference •

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 •

Unspecified vulnerability in certain versions of xpdf after 3.00, as used in various products including (a) pdfkit.framework, (b) gpdf, (c) pdftohtml, and (d) libextractor, has unknown impact and user-assisted attack vectors, possibly involving errors in (1) gmem.c, (2) SplashXPathScanner.cc, (3) JBIG2Stream.cc, (4) JPXStream.cc, and/or (5) Stream.cc. NOTE: this description is based on Debian advisory DSA 979, which is based on changes that were made after other vulnerabilities such as CVE-2006-0301 and CVE-2005-3624 through CVE-2005-3628 were fixed. Some of these newer fixes appear to be security-relevant, although it is not clear if they fix specific issues or are defensive in nature. • http://secunia.com/advisories/18948 http://secunia.com/advisories/19021 http://secunia.com/advisories/19065 http://secunia.com/advisories/19091 http://secunia.com/advisories/19164 http://secunia.com/advisories/19364 http://secunia.com/advisories/19644 http://security.debian.org/pool/updates/main/p/pdfkit.framework/pdfkit.framework_0.8-2sarge3.diff.gz http://www.debian.org/security/2006/dsa-1019 http://www.debian.org/security/2006/dsa-979 http://www.debian.org/security&#x •
