  descriptionDenial of service in Qmail by specifying a large number of recipients with the RCPT command.
  phaseModified (20010301-02)
  votesACCEPT(4) Baker, Frech, Hill, Meunier | REVIEWING(1) Christey
  commentsChristey> DUPE CVE-1999-0418 and CVE-1999-0250? | 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> http://cr.yp.to/qmail/venema.html | Berstein rejects this as a vulnerability, claiming this is a slander campaign by Wietse Venema. | His page states this is not a qmail problem, rather it is a UNIX problem | that many apps can consume all available memory, and that the administrator | is responsible to set limits in the OS, rather than expect applications to | individually prevent memory exhaustion. CAN 1999-0250 does appear to | be a duplicate of this entry, based on the research I have done so far. | There were two different bugtraq postings, but the second one references | the first, stating that the new exploit uses perl instead of shell scripting | to accomplish the same attack/exploit. | Baker> http://www.securityfocus.com/archive/1/6970 | http://www.securityfocus.com/archive/1/6969 | http://cr.yp.to/qmail/venema.html | | Should probably reject CVE-1999-0250, and add these references to this | Candidate. | Baker> http://www.securityfocus.com/bid/2237 | CHANGE> [Baker changed vote from REVIEWING to ACCEPT] | Christey> 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. | | NOTE: the ufo.org domain was purchased by another party in | 2003, so the current owner is not associated with any | statements by "super@ufo.org" that were made before 2003. | | 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 BID:2237 | ADDREF BUGTRAQ:19970612 qmail-dos-2.c, another denial of service attack | ADDREF BUGTRAQ:19970612 Re: Denial of service (qmail-smtpd) | | 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."
