Vulnerabilidades

Sendmail 8.12.0 through 8.12.6 truncates log messages longer than 100 characters, which allows remote attackers to prevent the IP address from being logged via a long IDENT response.

Sendmail Consortium's Restricted Shell (SMRSH) in Sendmail 8.12.6, 8.11.6-15, and possibly other versions after 8.11 from 5/19/1998, allows attackers to bypass the intended restrictions of smrsh by inserting additional commands after (1) "||" sequences or (2) "/" characters, which are not properly filtered or verified.

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.

Directory traversal vulnerability in sendform.cgi 1.44 and earlier allows remote attackers to read arbitrary files by specifying the desired files in the BlurbFilePath parameter.

phpsmssend.php in PhpSmsSend 1.0 allows remote attackers to execute arbitrary commands via an SMS message containing shell metacharacters.

Sendpage.pl allows remote attackers to execute arbitrary commands via a message containing shell metacharacters.

Sendmail before 8.12.1, without the RestrictQueueRun option enabled, allows local users to cause a denial of service (data loss) by (1) setting a high initial message hop count option (-h), which causes Sendmail to drop queue entries, (2) via the -qR option, or (3) via the -qS option.

Sendmail before 8.12.1 does not properly drop privileges when the -C option is used to load custom configuration files, which allows local users to gain privileges via malformed arguments in the configuration file whose names contain characters with the high bit set, such as (1) macro names that are one character…

Sendmail before 8.12.1, without the RestrictQueueRun option enabled, allows local users to obtain potentially sensitive information about the mail queue by setting debugging flags to enable debug mode.

Sendmail 8.10.0 through 8.11.5, and 8.12.0 beta, allows local users to modify process memory and possibly gain privileges via a large value in the 'category' part of debugger (-d) command line arguments, which is interpreted as a negative number.

sendfiled, as included with Simple Asynchronous File Transfer (SAFT), on various Linux systems does not properly drop privileges when sending notification emails, which allows local attackers to gain privileges.

Sendmail before 8.11.4, and 8.12.0 before 8.12.0.Beta10, allows local users to cause a denial of service and possibly corrupt the heap and gain privileges via race conditions in signal handlers.

Directory traversal vulnerability in sendtemp.pl in W3.org Anaya Web development server allows remote attackers to read arbitrary files via a .. (dot dot) attack in the templ parameter.

mail.local in Sendmail 8.10.x does not properly identify the .\n string which identifies the end of message text, which allows a remote attacker to cause a denial of service or corrupt mailboxes via a message line that is 2047 characters long and ends in .\n.

Multiple unspecified vulnerabilities in sendmail 5, as installed on Sun SunOS 4.1.3_U1 and 4.1.4, have unspecified attack vectors and impact. NOTE: this might overlap CVE-1999-0129.

Sendmail before 8.10.0 allows remote attackers to cause a denial of service by sending a series of ETRN commands then disconnecting from the server, while Sendmail continues to process the commands after the connection has been terminated.

Sendmail allows local users to reinitialize the aliases database via the newaliases command, then cause a denial of service by interrupting Sendmail.

Denial of service in Sendmail 8.8.6 in HPUX.

Denial of service in SMTP applications such as Sendmail, when a remote attacker (e.g. spammer) uses many "RCPT TO" commands in the same connection.

The metamail package allows remote command execution using shell metacharacters that are not quoted in a mailcap entry.

Remote attackers can cause a denial of service in Sendmail 8.8.x and 8.9.2 by sending messages with a large number of headers.

A system is running a version of software that was replaced with a Trojan Horse at one of its distribution points, such as (1) TCP Wrappers 7.6, (2) util-linux 2.9g, (3) wuarchive ftpd (wuftpd) 2.2 and 2.1f, (4) IRC client (ircII) ircII 2.2.9, (5) OpenSSH 3.4p1, or (6) Sendmail 8.12.6.

Denial of service in Sendmail 8.6.11 and 8.6.12.

A Sendmail alias allows input to be piped to a program.

Denial of service in HP-UX sendmail 8.8.6 related to accepting connections.
