CVE-2026-9365
MediumCVSS 5.6Exploitation Probability (EPSS)
Low risk24th percentile - higher than 24% of all known CVEs
Summary
In Ettercap up to version 0.8.3, a heap-based buffer overflow exists in the FUNC_DECODER function of the GG Dissector component (file ec_gg.c). Manipulation of the gg argument can lead to a remote attack, though exploitation is difficult.
Risk Assessment
A successful attack could allow arbitrary code execution in the context of Ettercap, potentially leading to tool compromise and further network attacks.
Recommendation
Upgrade Ettercap to version 0.8.4, which contains the fix (commit feeae6fa366e01a3dd9f1857ec6aae847b2ae00c).
Other vulnerabilities in Ettercap
See all- CVE-2014-9379High
The radius_get_attribute function in Ettercap 0.8.1 performs an incorrect cast, allowing remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via unspecified vectors, leading to a stack-based buffer overflow.
- CVE-2014-9378High
Ettercap version 0.8.1 does not validate certain return values, allowing remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted data passed to the parse_line or dissector_imap functions.
- CVE-2014-9377High
A heap-based buffer overflow in the nbns_spoof function in Ettercap 0.8.1 can be exploited by remote attackers. Attackers can cause a denial of service or potentially execute arbitrary code by sending a large netbios packet.
- CVE-2014-9376High
An integer underflow in Ettercap 0.8.1 allows remote attackers to cause a denial of service (out-of-bounds write) and possibly execute arbitrary code. This can occur in several functions, including dissector_dhcp, dissector_gg, and dissector_TN3270.
- CVE-2014-6396High
The dissector_postgresql function in Ettercap before version 0.8.1 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted password length, which triggers a 0 character to be written to an arbitrary memory location.
- CVE-2017-8366Critical
The strescape function in ec_strings.c in Ettercap 0.8.2 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted filter that is mishandled by etterfilter.
Original NVD description (English source)
A vulnerability has been found in Ettercap up to 0.8.3. The affected element is the function FUNC_DECODER of the file src/dissectors/ec_gg.c of the component GG Dissector. The manipulation of the argument gg leads to heap-based buffer overflow. The attack is possible to be carried out remotely. The complexity of an attack is rather high. The exploitability is described as difficult. The exploit has been disclosed to the public and may be used. Upgrading to version 0.8.4 is sufficient to fix this issue. The identifier of the patch is feeae6fa366e01a3dd9f1857ec6aae847b2ae00c. It is suggested to upgrade the affected component.
