https://notcve.org/view.php?id=CVE-2011-4862
Buffer overflow in libtelnet/encrypt.c in telnetd in FreeBSD 7.3 through 9.0, MIT Kerberos Version 5 Applications (aka krb5-appl) 1.0.2 and earlier, Heimdal 1.5.1 and earlier, GNU inetutils, and possibly other products allows remote attackers to execute arbitrary code via a long encryption key, as exploited in the wild in December 2011. Desbordamiento de búfer basado en pila en libtelnet/encrypt.c en telnetd en FreeBSD v7.3 hasta v9.0, MIT Kerberos Version v5 Applications (también conocido como krb5-appl) v1.0.2 y anteriores, y Heimdal v1.5.1 y anteriores, permite a atacantes remotos ejecutar código de su elección a través de una clave de cifrado larga, como fue explotado en Diciembre 2011.

https://notcve.org/view.php?id=CVE-2011-0762
The vsf_filename_passes_filter function in ls.c in vsftpd before 2.3.3 allows remote authenticated users to cause a denial of service (CPU consumption and process slot exhaustion) via crafted glob expressions in STAT commands in multiple FTP sessions, a different vulnerability than CVE-2010-2632. La función vsf_filename_passes_filter de ls.c de vsftpd en versiones anteriores a la 2.3.3 permite a usuarios autenticados remotos provocar una denegación de servicio (consumo de toda la CPU y agotamiento de los slots de procesos) a través de una expresión glob modificada en comandos STAT en múltiples sesiones FTP. Una vulnerabilidad distinta a la CVE-2010-2632. Vsftpd versions 2.3.2 on NetBSD and 2.3.0 on Ubuntu suffer from a remote denial of service vulnerability. • https://www.exploit-db.com/exploits/16270 ftp://vsftpd.beasts.org/users/cevans/untar/vsftpd-2.3.4/Changelog http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=622741 http://cxib.net/stuff/vspoc232.c http://jvn.jp/en/jp/JVN37417423/index.html http://lists.fedoraproject.org/pipermail/package-announce/2011-March/055881.html http://lists.fedoraproject.org/pipermail/package-announce/2011-March/055882.html http://lists.fedoraproject.org/pipermail/package-announce/2011-March/055957.html http&# • CWE-400: Uncontrolled Resource Consumption •
