Arch Linux ASA-201503-12 High: Ettercap Code Execution Threats

The package ettercap before version 0.8.2-1 is vulnerable to multiple issues including but not limited to arbitrary code execution, arbitrary memory write and denial of service. . Arch Linux Security Advisory ASA-201503-12 ========================================= Severity: High Date : 2015-03-17 CVE-ID : CVE-2014-6395 CVE-2014-6396 CVE-2014-9376 CVE-2014-9377 CVE-2014-9378 CVE-2014-9379 CVE-2014-9380 CVE-2014-9381 Package : ettercap Type : multiple issues Remote : Yes Link : https://wiki.archlinux.org/title/CVE Summary ====== The package ettercap before version 0.8.2-1 is vulnerable to multiple issues including but not limited to arbitrary code execution, arbitrary memory write and denial of service. Resolution ========= Upgrade to 0.8.2-1. # pacman -Syu "ettercap> =0.8.2-1" The problems have been fixed upstream in version 0.8.2. Workaround ========= None. Description ========== - CVE-2014-6395 (arbitrary code execution) Heap-based buffer overflow in the dissector_postgresql function in dissectors/ec_postgresql.c allows remote attackers to cause a denial of service or possibly execute arbitrary code via a crafted password length value that is inconsistent with the actual length of the password. - CVE-2014-6396 (arbitrary memory write) The dissector_postgresql function in dissectors/ec_postgresql.c 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-2014-9376 (arbitrary code execution) Integer underflow allows remote attackers to cause a denial of service (out-of-bounds write) and possibly execute arbitrary code via a small (1) size variable value in the dissector_dhcp function in dissectors/ec_dhcp.c, (2) length value to the dissector_gg function in dissectors/ec_gg.c, or (3) string length to the get_decode_len function in ec_utils.c or a request without a (4) username or (5)password to the dissector_TN3270 function in dissectors/ec_TN3270.c. - CVE-2014-9377 (arbitrary code execution) Heap-based buffer overflow in the nbns_spoof function in plug-ins/nbns_spoof/nbns_spoof.c allows remote attackers to cause a denial of service or possibly execute arbitrary code via a large netbios packet. - CVE-2014-9378 (arbitrary code execution) Ettercap does not validate certain return values, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted (1) name to the parse_line function in mdns_spoof/mdns_spoof.c or (2) base64 encoded password to the dissector_imap function in dissectors/ec_imap.c. - CVE-2014-9379 (arbitrary code execution) The radius_get_attribute function in dissectors/ec_radius.c performs an incorrect cast, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via unspecified vectors, which triggers a stack-based buffer overflow. - CVE-2014-9380 (denial of service) The dissector_cvs function in dissectors/ec_cvs.c allows remote attackers to cause a denial of service (out-of-bounds read) via a packet containing only a CVS_LOGIN signature. - CVE-2014-9381 (denial of service) Integer signedness error in the dissector_cvs function in dissectors/ec_cvs.c allows remote attackers to cause a denial of service (crash) via a crafted password, which triggers a large memory allocation. Impact ===== A remote attacker is able to send specially crafted packets to perform arbitrary code execution, arbitrary memory write or denial of service via variousvectors.
