IPSEC implementations including (1) FreeS/WAN and (2) KAME do not properly calculate the length of authentication data, which allows remote attackers to cause a denial of service (kernel panic) via spoofed, short Encapsulating Security Payload (ESP) packets, which result in integer signedness errors. Implementaciones de IPSEC, incluyendo FreeS/WAN y KAME no calculan adecuadamente la longitud de los datos de autenticación, lo que permite a atacantes remotos causar una denegación de servicio (kernel panic) mediante paquetes Encapsulating Security Payload (EPS) cortos falsificados, lo que resulta en errores de enteros sin signos. • ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2002-016.txt.asc http://razor.bindview.com/publish/advisories/adv_ipsec.html http://www.debian.org/security/2002/dsa-201 http://www.iss.net/security_center/static/10411.php http://www.kb.cert.org/vuls/id/459371 http://www.securityfocus.com/bid/6011 •

Heap corruption vulnerability in the "at" program allows local users to execute arbitrary code via a malformed execution time, which causes at to free the same memory twice. Corrupción de memoria en el comando "at" permite que usuarios locales ejecuten código arbitrario haciendo uso de un tiempo de ejecución mal escrito (lo que provoca que at libere la misma memoria dos veces). • https://www.exploit-db.com/exploits/21229 http://marc.info/?l=bugtraq&m=101128661602088&w=2 http://marc.info/?l=bugtraq&m=101147632721031&w=2 http://online.securityfocus.com/advisories/3833 http://online.securityfocus.com/advisories/3969 http://www.debian.org/security/2002/dsa-102 http://www.novell.com/linux/security/advisories/2002_003_at_txt.html http://www.redhat.com/support/errata/RHSA-2002-015.html http://www.securityfocus.com/bid/3886 https://exchange.xforce. •

Buffer overflow in BSD-based telnetd telnet daemon on various operating systems allows remote attackers to execute arbitrary commands via a set of options including AYT (Are You There), which is not properly handled by the telrcv function. • https://www.exploit-db.com/exploits/21018 ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-01:49.telnetd.asc ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2001-012.txt.asc ftp://patches.sgi.com/support/free/security/advisories/20010801-01-P ftp://stage.caldera.com/pub/security/openserver/CSSA-2001-SCO.10/CSSA-2001-SCO.10.txt http://archives.neohapsis.com/archives/hp/2001-q4/0014.html http://distro.conectiva.com.br/atualizacoes/?id=a&anuncio=000413 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

Buffer overflows in BSD-based FTP servers allows remote attackers to execute arbitrary commands via a long pattern string containing a {} sequence, as seen in (1) g_opendir, (2) g_lstat, (3) g_stat, and (4) the glob0 buffer as used in the glob functions glob2 and glob3. • https://www.exploit-db.com/exploits/20731 https://www.exploit-db.com/exploits/20732 https://www.exploit-db.com/exploits/20733 ftp://ftp.NetBSD.ORG/pub/NetBSD/misc/security/advisories/NetBSD-SA2000-018.txt.asc ftp://patches.sgi.com/support/free/security/advisories/20010802-01-P http://archives.neohapsis.com/archives/freebsd/2001-04/0466.html http://www.cert.org/advisories/CA-2001-07.html http://www.nai.com/research/covert/advisories/048.asp http://www.securityfocus.com&#x •

The undocumented semconfig system call in BSD freezes the state of semaphores, which allows local users to cause a denial of service of the semaphore system by using the semconfig call. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-00:19.semconfig.asc ftp://ftp.netbsd.org/pub/NetBSD/misc/security/advisories/NetBSD-SA2000-004.txt.asc http://www.openbsd.org/errata26.html#semconfig http://www.securityfocus.com/bid/1270 •
