Vulnerability from variot - Updated: 2025-04-10 22:57Ipswitch IMail Server 2006 before 2006.21 allows remote attackers to cause a denial of service (daemon crash) via unspecified vectors involving an "overwritten destructor.". Ipswitch IMail Server 2006 There is a service disruption ( Daemon crash ) There is a vulnerability that becomes a condition.Service disruption by a third party ( Daemon crash ) There is a possibility of being put into a state. Imail Server is prone to a denial-of-service vulnerability.

TITLE: Ipswitch IMail Server/Collaboration Suite Multiple Buffer Overflows
SECUNIA ADVISORY ID: SA26123
VERIFY ADVISORY: http://secunia.com/advisories/26123/
CRITICAL: Highly critical
IMPACT: System access
WHERE:
From remote
SOFTWARE: IMail Server 2006 http://secunia.com/product/8653/ Ipswitch Collaboration Suite 2006 http://secunia.com/product/8652/
DESCRIPTION: Some vulnerabilities have been reported in Ipswitch IMail Server and Collaboration Suite, which can be exploited by malicious users and malicious people to compromise a vulnerable system.
1) A boundary error in the processing of the IMAP "SEARCH" command can be exploited to cause a stack-based buffer overflow.
Successful exploitation allows execution of arbitrary code, but requires a valid user account.
2) A boundary error in the processing of the IMAP "SEARCH CHARSET" command can be exploited to cause a heap-based buffer overflow.
Successful exploitation allows execution of arbitrary code, but requires a valid user account.
Vulnerabilities #1 and #2 are reported in version 6.8.8.1 of imapd32.exe. Prior versions may also be affected.
3) A boundary error in Imailsec can be exploited to cause a heap-based buffer overflow and allows execution of arbitrary code.
4) A boundary error in "subscribe" can be exploited to cause a buffer overflow. No further information is currently available.
Vulnerabilities #3 and #4 are reported in Ipswitch IMail Server and Collaboration Suite prior to version 2006.21.
SOLUTION: Update to IMail Server version 2006.21. http://www.ipswitch.com/support/imail/releases/im200621.asp
Update to Ipswitch Collaboration Suite 2006.21. http://www.ipswitch.com/support/ics/updates/ics200621.asp
PROVIDED AND/OR DISCOVERED BY: 1) Manuel Santamarina Suarez, reported via iDefense Labs. 2) An anonymous person, reported via iDefense Labs. 3, 4) The vendor credits TippingPoint and the Zero Day Initiative.

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
