CVE-2011-2362

SeaMonkey through 2.0.14 - Same Origin Policy Bypass via Trailing Dot Cookie Domain

Title source: llm
STIX 2.1

Description

Mozilla Firefox before 3.6.18, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14 do not distinguish between cookies for two domain names that differ only in a trailing dot, which allows remote web servers to bypass the Same Origin Policy via Set-Cookie headers.
