The DNS map code in Sendmail 8.12.8 and earlier, when using the "enhdnsbl" feature, does not properly initialize certain data structures, which allows remote attackers to cause a denial of service (process crash) via an invalid DNS response that causes Sendmail to free incorrect data. • ftp://patches.sgi.com/support/free/security/advisories/20030803-01-P http://distro.conectiva.com.br/atualizacoes/?id=a&anuncio=000727 http://www.kb.cert.org/vuls/id/993452 http://www.mandriva.com/security/advisories?name=MDKSA-2003:086 http://www.novell.com/linux/security/advisories/2003_035_sendmail.html http://www.redhat.com/support/errata/RHSA-2003-265.html http://www.sendmail.org/dnsmap1.html https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef •

The prescan() function in the address parser (parseaddr.c) in Sendmail before 8.12.9 does not properly handle certain conversions from char and int types, which can cause a length check to be disabled when Sendmail misinterprets an input value as a special "NOCHAR" control value, allowing attackers to cause a denial of service and possibly execute arbitrary code via a buffer overflow attack using messages, a different vulnerability than CVE-2002-1337. • https://www.exploit-db.com/exploits/24 https://www.exploit-db.com/exploits/22442 ftp://ftp.caldera.com/pub/security/OpenLinux/CSSA-2003-016.0.txt ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-03:07.sendmail.asc ftp://ftp.sco.com/pub/updates/OpenServer/SCOSA-2004.11/SCOSA-2004.11.txt ftp://patches.sgi.com/support/free/security/advisories/20030401-01-P http://distro.conectiva.com.br/atualizacoes/?id=a&anuncio=000614 http://lists.apple.com/mhonarc/secur •
