CVE-2026-125401 2 Ettercap, Ettercap-project 2 Ettercap, Ettercap 2026-11-10 8.1 High
Ettercap through 0.8.4.1 contains a heap buffer overflow vulnerability in gg_get_version() in src/dissectors/ec_gg.c that writes up to 44 bytes into a 30-byte allocation. Remote attackers can send Gadu-Gadu traffic on TCP port 8074 with a crafted version field through a monitored network to corrupt heap memory in the Ettercap process, which normally runs as root.
CVE-2026-125400 2 Ettercap, Ettercap-project 2 Ettercap, Ettercap 2026-11-10 8.8 High
Ettercap through 0.8.4.1 contains a use-after-free vulnerability in func_pcre() in src/ec_filter.c that reads the PCRE2 ovector after freeing match data. Network-adjacent attackers can send packets matching a loaded pcre_regex() substitution filter to corrupt memory and potentially execute code as root.
CVE-2026-125406 2 Ettercap, Ettercap-project 2 Ettercap, Ettercap 2026-11-10 8.8 High
Ettercap through 0.8.4.1 contains a stack buffer underwrite vulnerability in the telnet dissector in src/dissectors/ec_telnet.c that decrements the output pointer on backspace without a lower bound check. Attackers can send a telnet stream with more backspaces than preceding characters to write below the stack buffer, corrupting the stack of the Ettercap process that normally runs as root.
CVE-2026-125404 2 Ettercap, Ettercap-project 2 Ettercap, Ettercap 2026-11-10 7.5 High
Ettercap through 0.8.4.1 contains an integer underflow in ccmp_decrypt() in src/ec_encryption_ccmp.c that subtracts the 8-byte CCMP trailer without checking minimum length. Attackers on a network whose WPA key is loaded can send a short crafted CCMP frame to overflow a stack buffer in the Ettercap process, which normally runs as root.
CVE-2026-9365 1 Ettercap 1 Ettercap 2026-05-26 5.6 Medium
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.
CVE-2026-3606 2 Ettercap, Ettercap-project 2 Ettercap, Ettercap 2026-04-16 3.3 Low
A vulnerability has been found in Ettercap 0.8.4-Garofalo. Affected by this vulnerability is the function add_data_segment of the file src/ettercap/utils/etterfilter/ef_output.c of the component etterfilter. The manipulation leads to out-of-bounds read. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2002-0276 1 Ettercap 1 Ettercap 2026-04-16 N/A
Buffer overflow in various decoders in Ettercap 0.6.3.1 and earlier, when running on networks with an MTU greater than 2000, allows remote attackers to execute arbitrary code via large packets.
CVE-2005-1796 2 Debian, Ettercap 2 Debian Linux, Ettercap 2026-04-16 N/A
Format string vulnerability in the curses_msg function in the Ncurses interface (ec_curses.c) for Ettercap before 0.7.3 allows remote attackers to execute arbitrary code.
