VAR-200512-0696
Vulnerability from variot - Updated: 2025-04-03 22:26Ingate Firewall before 4.3.4 and SIParator before 4.3.4 allows remote attackers to cause a denial of service (kernel deadlock) by sending a SYN packet for a TCP stream, which requires an RST packet in response. Ingate Firewall and SIParator products are susceptible to a remote denial of service vulnerability.
TITLE: Ingate Firewall and SIParator Denial of Service Vulnerability
SECUNIA ADVISORY ID: SA18138
VERIFY ADVISORY: http://secunia.com/advisories/18138/
CRITICAL: Moderately critical
IMPACT: DoS
WHERE:
From remote
OPERATING SYSTEM: Ingate SIParator 4.x http://secunia.com/product/5687/ Ingate Firewall 4.x http://secunia.com/product/4050/
DESCRIPTION: A vulnerability has been reported in Ingate Firewall and SIParator, which potentially can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in the kernel when handling certain TCP packets in a media stream.
SOLUTION: Update to version 4.3.4. http://www.ingate.com/upgrades.php
PROVIDED AND/OR DISCOVERED BY: Reported by vendor.

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.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
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.
