CVE-2002-1827 [LOW] CVE-2002-1827: Sendmail 8.9.0 through 8.12.3 allows local users to cause a denial of service by obtaining an exclus Sendmail 8.9.0 through 8.12.3 allows local users to cause a denial of service by obtaining an exclusive lock on the (1) alias, (2) map, (3) statistics, and (4) pid files.

CVE-2004-0833 [HIGH] CVE-2004-0833: Sendmail before 8 Sendmail before 8.12.3 on Debian GNU/Linux, when using sasl and sasl-bin, uses a Sendmail configuration script with a fixed username and password, which could allow remote attackers to use Sendmail as an open mail relay and send spam messages.

CVE-2023-51765 [MEDIUM] CWE-345 CVE-2023-51765: sendmail through 8.17.2 allows SMTP smuggling in certain configurations. Remote attackers can use a sendmail through 8.17.2 allows SMTP smuggling in certain configurations. Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because sendmail supports . but some other popular e-mail servers do not. This is resolved in 8.18

CVE-2002-0906 [HIGH] CVE-2002-0906: Buffer overflow in Sendmail before 8.12.5, when configured to use a custom DNS map to query TXT reco Buffer overflow in Sendmail before 8.12.5, when configured to use a custom DNS map to query TXT records, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a malicious DNS server.
