| CVE-2006-4434 | Hig | 0.49 | 7.5 | 0.07 | | Aug 29, 2006 | Use-after-free vulnerability in Sendmail before 8.13.8 allows remote attackers to cause a denial of service (crash) via a long "header line", which causes a previously freed variable to be referenced. NOTE: the original developer has disputed the severity of this issue, saying "The only denial of service that is possible here is to fill up the disk with core dumps if the OS actually generates different core dumps (which is unlikely)... the bug is in the shutdown code (finis()) which leads directly to exit(3), i.e., the process would terminate anyway, no mail delivery or receiption is affected." |
| CVE-2003-0694 | | 0.09 | — | 0.76 | | Oct 6, 2003 | The prescan function in Sendmail 8.12.9 allows remote attackers to execute arbitrary code via buffer overflow attacks, as demonstrated using the parseaddr function in parseaddr.c. |
| CVE-2006-0058 | | 0.08 | — | 0.59 | | Mar 22, 2006 | Signal handler race condition in Sendmail 8.13.x before 8.13.6 allows remote attackers to execute arbitrary code by triggering timeouts in a way that causes the setjmp and longjmp function calls to be interrupted and modify unexpected memory locations. |
| CVE-2003-0161 | | 0.08 | — | 0.68 | | Apr 2, 2003 | 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. |
| CVE-2002-1337 | | 0.07 | — | 0.44 | | Mar 7, 2003 | Buffer overflow in Sendmail 5.79 to 8.12.7 allows remote attackers to execute arbitrary code via certain formatted address fields, related to sender and recipient header comments as processed by the crackaddr function of headers.c. |
| CVE-2009-1490 | | 0.04 | — | 0.08 | | May 5, 2009 | Heap-based buffer overflow in Sendmail before 8.13.2 allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via a long X- header, as demonstrated by an X-Testing header. |
| CVE-2003-0681 | | 0.04 | — | 0.12 | | Oct 6, 2003 | A "potential buffer overflow in ruleset parsing" for Sendmail 8.12.9, when using the nonstandard rulesets (1) recipient (2), final, or (3) mailer-specific envelope recipients, has unknown consequences. |
| CVE-1999-1109 | | 0.04 | — | 0.08 | | Dec 22, 1999 | 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. |
| CVE-2002-1827 | | 0.03 | — | 0.01 | | Dec 31, 2002 | 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-2002-1165 | | 0.03 | — | 0.01 | | Oct 11, 2002 | 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. |
| CVE-2001-0653 | | 0.03 | — | 0.00 | | Sep 20, 2001 | 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. |
| CVE-2006-1173 | | 0.02 | — | 0.21 | | Jun 7, 2006 | Sendmail before 8.13.7 allows remote attackers to cause a denial of service via deeply nested, malformed multipart MIME messages that exhaust the stack during the recursive mime8to7 function for performing 8-bit to 7-bit conversion, which prevents Sendmail from delivering queued messages and might lead to disk consumption by core dump files. |
| CVE-2014-3956 | | 0.00 | — | 0.00 | | Jun 4, 2014 | The sm_close_on_exec function in conf.c in sendmail before 8.14.9 has arguments in the wrong order, and consequently skips setting expected FD_CLOEXEC flags, which allows local users to access unintended high-numbered file descriptors via a custom mail-delivery program. |
| CVE-2009-4565 | | 0.00 | — | 0.01 | | Jan 4, 2010 | sendmail before 8.14.4 does not properly handle a '\0' character in a Common Name (CN) field of an X.509 certificate, which (1) allows man-in-the-middle attackers to spoof arbitrary SSL-based SMTP servers via a crafted server certificate issued by a legitimate Certification Authority, and (2) allows remote attackers to bypass intended access restrictions via a crafted client certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408. |
| CVE-2007-2246 | | 0.00 | — | 0.03 | | Apr 25, 2007 | Unspecified vulnerability in HP-UX B.11.00 and B.11.11, when running sendmail 8.9.3 or 8.11.1; and HP-UX B.11.23 when running sendmail 8.11.1; allows remote attackers to cause a denial of service via unknown attack vectors. NOTE: due to the lack of details from HP, it is not known whether this issue is a duplicate of another CVE such as CVE-2006-1173 or CVE-2006-4434. |
| CVE-2006-7176 | | 0.00 | — | 0.01 | | Mar 27, 2007 | The version of Sendmail 8.13.1-2 on Red Hat Enterprise Linux 4 Update 4 and earlier does not reject the "localhost.localdomain" domain name for e-mail messages that come from external hosts, which might allow remote attackers to spoof messages. |
| CVE-2006-7175 | | 0.00 | — | 0.00 | | Mar 27, 2007 | The version of Sendmail 8.13.1-2 on Red Hat Enterprise Linux 4 Update 4 and earlier does not allow the administrator to disable SSLv2 encryption, which could cause less secure channels to be used than desired. |
| CVE-2005-2070 | | 0.00 | — | 0.01 | | Jun 29, 2005 | The ClamAV Mail fILTER (clamav-milter) 0.84 through 0.85d, when used in Sendmail using long timeouts, allows remote attackers to cause a denial of service by keeping an open connection, which prevents ClamAV from reloading. |
| CVE-2003-0688 | | 0.00 | — | 0.02 | | Oct 20, 2003 | 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. |
| CVE-2003-0308 | | 0.00 | — | 0.00 | | May 15, 2003 | The Sendmail 8.12.3 package in Debian GNU/Linux 3.0 does not securely create temporary files, which could allow local users to gain additional privileges via (1) expn, (2) checksendmail, or (3) doublebounce.pl. |
