Balabit Syslog-NG 1.4.x before 1.4.15, and 1.5.x before 1.5.20, when using template filenames or output, does not properly track the size of a buffer when constant characters are encountered during macro expansion, which allows remote attackers to cause a denial of service and possibly execute arbitrary code. Balabit Syslog-NG 1.4.x antes de 1.4.15, y 1.4.x antes de 1.5.20, cuando se usan plantillas de nombres de fichero o de salida, no controla adecuadamente el tamaño de un búfer cuando se encuentran caracteres constantes durante una expansión de macro, lo que permite a atacantes remotos causar una denegación de servicio y posiblemente ejecutar código arbitrario. • http://distro.conectiva.com.br/atualizacoes/?id=a&anuncio=000547 http://marc.info/?l=bugtraq&m=103426595021928&w=2 http://www.balabit.hu/static/zsa/ZSA-2002-014-en.txt http://www.debian.org/security/2002/dsa-175 http://www.iss.net/security_center/static/10339.php http://www.linuxsecurity.com/advisories/other_advisory-2513.html http://www.novell.com/linux/security/advisories/2002_039_syslog_ng.html http://www.securityfocus.com/bid/5934 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
