  descriptionDenial of service in Qmail through long SMTP commands.

  commentsFrech> XF:qmail-rcpt | Christey> DUPE CVE-1999-0418 and CVE-1999-0144? | Christey> Dan Bernstein, author of Qmail, says that this is not a | vulnerability in qmail because Unix has built-in resource | limits that can restrict the size of a qmail process; other | limits can be specified by the administrator. See | http://cr.yp.to/qmail/venema.html | | Significant discussion of this issue took place on the qmail | list. The fundamental question appears to be whether | application software should set its own limits, or rely | on limits set by the parent operating system (in this case, | UNIX). Also, some people said that the only problem was that | the suggested configuration was not well documented, but this | was refuted by others. | | See the following threads at | http://www.ornl.gov/its/archives/mailing-lists/qmail/1997/06/threads.html | "Denial of service (qmail-smtpd)" | "qmail-dos-2.c, another denial of service" | "[PATCH] denial of service" | "just another qmail denial-of-service" | "the UNIX way" | "Time for a reality check" | | Also see Bugtraq threads on a different vulnerability that | is related to this topic: | BUGTRAQ:19990903 Web servers / possible DOS Attack / mime header flooding | http://archives.neohapsis.com/archives/bugtraq/1998_3/0742.html | Baker> This appears to be the same vulnerability listed in CAN 1999-0144. In reading | through both bugtraq postings, the one that is referenced by 0144 is | based on a shell code exploit to cause memory exhaustion. The bugtraq | posting referenced by this entry refers explicitly to the prior | posting for 0144, and states that the same effect could be | accomplished by a perl exploit, which was then attached. | Baker> http://www.securityfocus.com/archive/1/6969 CVE-1999-0144 | http://www.securityfocus.com/archive/1/6970 CVE-1999-0250 | | Both references should be added to CVE-1999-0144, and CVE-1999-0250 | should likely be rejected. | CHANGE> [Baker changed vote from REVIEWING to REJECT] | Christey> XF:qmail-leng no longer exists; check with Andre to see if they | regarded it as a duplicate as well. | | qmail-dos-1.c, as published by Wietse Venema (CVE-1999-0250) | in "BUGTRAQ:19970612 Denial of service (qmail-smtpd)", does not | use any RCPT commands. Instead, it sends long strings | of "X" characters. A followup by "super@UFO.ORG" includes | an exploit that claims to do the same thing; however, that | exploit does not send long strings of X characters - it sends | a large number of RCPT commands. It appears that super@ufo.org | followed up to the wrong message. | | qmail-dos-2.c, as published by Wietse Venema (CVE-1999-0144) | in "BUGTRAQ:19970612 qmail-dos-2.c, another denial of service attack" | sends a large number of RCPT commands. | | ADDREF BUGTRAQ:19970612 Denial of service (qmail-smtpd) | ADDREF BUGTRAQ:19970612 qmail-dos-2.c, another denial of service attack | | Also see a related thread: | BUGTRAQ:19990308 SMTP server account probing | http://marc.theaimsgroup.com/?l=bugtraq&m=92100018214316&w=2 | | This also describes a problem with mail servers not being able | to handle too many "RCPT TO" requests. A followup message | notes that application-level protection is used in Sendmail | to prevent this: | BUGTRAQ:19990309 Re: SMTP server account probing | http://marc.theaimsgroup.com/?l=bugtraq&m=92101584629263&w=2 | The person further says, "This attack can easily be | prevented with configuration methods."
