The OLE2 parser in Clam AntiVirus (ClamAV) allows remote attackers to cause a denial of service (resource consumption) via an OLE2 file with (1) a large property size or (2) a loop in the FAT file block chain that triggers an infinite loop, as demonstrated via a crafted DOC file. El analazidor sintáctico OLE2 en Clam AntiVirus (ClamAV) permite a atacantes remotos provocar denegación de servicio (consumo de recursos) a través de un archivo OLE2 con (1)un tamaño grande de la propiedad o (2) un bucle en la cadena del bloque del archivo del FAT que dispara un bucle infinito, como se demostró a través de un archivo DOC manipulado. • http://article.gmane.org/gmane.comp.security.virus.clamav.devel/2853 http://kolab.org/security/kolab-vendor-notice-15.txt http://lurker.clamav.net/message/20070418.111144.0df6c5d3.en.html http://secunia.com/advisories/25244 http://secunia.com/advisories/25523 http://secunia.com/advisories/25525 http://secunia.com/advisories/25553 http://secunia.com/advisories/25558 http://secunia.com/advisories/25688 http://secunia.com/advisories/25796 http://security.gentoo.org/glsa/glsa-200706& • CWE-400: Uncontrolled Resource Consumption •

Clam AntiVirus ClamAV before 0.90 does not close open file descriptors under certain conditions, which allows remote attackers to cause a denial of service (file descriptor consumption and failed scans) via CAB archives with a cabinet header record length of zero, which causes a function to return without closing a file descriptor. Clam AntiVirus ClamAV anterior a 0.90 no cierra los descriptores de apertura de ficheros bajo ciertas condiciones, lo cual permite a atacantes remotos provocar denegación de servicio (consumo del descriptor de fichero y fallo de escaneo) a través de archivos CAB con una longitud de registro con una cabecera cabinet(.CAB) de cero, lo cual provoca que una función retorne sin cerrar el descriptor de fichero. • http://docs.info.apple.com/article.html?artnum=307562 http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=475 http://lists.apple.com/archives/security-announce/2008/Mar/msg00001.html http://lists.suse.com/archive/suse-security-announce/2007-Feb/0004.html http://osvdb.org/32283 http://secunia.com/advisories/24183 http://secunia.com/advisories/24187 http://secunia.com/advisories/24192 http://secunia.com/advisories/24319 http://secunia.com/advisories/24332 http:/&# • CWE-772: Missing Release of Resource after Effective Lifetime •

Heap-based buffer overflow in the pefromupx function in libclamav/upx.c in Clam AntiVirus (ClamAV) 0.81 through 0.88.3 allows remote attackers to execute arbitrary code via a crafted UPX packed file containing sections with large rsize values. Desbordamiento de búfer basado en montón en la función pefromupx en libclamav/upx.c en Clam AntiVirus (ClamAV) 0.81 hasta 0.88.3 permite a atacantes remotos ejecutar código de su elección mediante un archivo empaquetado UPX manipulado que contiene secciones con valores grandes de rsize. • https://www.exploit-db.com/exploits/28348 http://kolab.org/security/kolab-vendor-notice-10.txt http://secunia.com/advisories/21368 http://secunia.com/advisories/21374 http://secunia.com/advisories/21433 http://secunia.com/advisories/21443 http://secunia.com/advisories/21457 http://secunia.com/advisories/21497 http://secunia.com/advisories/21562 http://security.gentoo.org/glsa/glsa-200608-13.xml http://securitytracker.com/id?1016645 http://www.clamav.net/security/0.88&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Multiple format string vulnerabilities in the logging code in Clam AntiVirus (ClamAV) before 0.88.1 might allow remote attackers to execute arbitrary code. NOTE: as of 20060410, it is unclear whether this is a vulnerability, as there is some evidence that the arguments are actually being sanitized properly. • http://lists.apple.com/archives/security-announce/2006/May/msg00003.html http://lists.suse.com/archive/suse-security-announce/2006-Apr/0002.html http://secunia.com/advisories/19534 http://secunia.com/advisories/19536 http://secunia.com/advisories/19564 http://secunia.com/advisories/19567 http://secunia.com/advisories/19570 http://secunia.com/advisories/19608 http://secunia.com/advisories/20077 http://secunia.com/advisories/23719 http://sourceforge.net/project/shownotes.php?release&# • CWE-134: Use of Externally-Controlled Format String •
