Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2014-9381)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Integer signedness error in the dissector_cvs function in dissectors/ec_cvs.c in Ettercap 0.8.1 allows remote attackers to cause a denial of service (crash) via a crafted password, which triggers a large memory allocation.


2) Buffer overflow (CVE-ID: CVE-2014-9380)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The dissector_cvs function in dissectors/ec_cvs.c in Ettercap 0.8.1 allows remote attackers to cause a denial of service (out-of-bounds read) via a packet containing only a CVS_LOGIN signature.


3) Stack-based buffer overflow (CVE-ID: CVE-2014-9379)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the radius_get_attribute function in dissectors/ec_radius.c when processing unspecified vectors, which triggers a stack-based buffer overflow. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


4) Input validation error (CVE-ID: CVE-2014-9378)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Ettercap 0.8.1 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.


5) Input validation error (CVE-ID: CVE-2014-9376)

The vulnerability allows remote attackers to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can 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.


6) Heap-based buffer overflow (CVE-ID: CVE-2014-9377)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Heap-based buffer overflow in the nbns_spoof function in plug-ins/nbns_spoof/nbns_spoof.c in Ettercap 0.8.1. A remote attacker can use a large netbios packet. to trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
