Summary
Several security issues were fixed in Thunderbird.
Software description
- thunderbird
– Mozilla Open Source mail and newsgroup client
Details
Christian Holler and Patrick McManus discovered multiple memory safety
issues in Thunderbird. If a user were tricked in to opening a specially
crafted message with scripting enabled, an attacker could potentially
exploit these to cause a denial of service via application crash, or
execute arbitrary code with the privileges of the user invoking
Thunderbird. (CVE-2014-8634)
Muneaki Nishimura discovered that requests from navigator.sendBeacon()
lack an origin header. If a user were tricked in to opening a specially
crafted message with scripting enabled, an attacker could potentially
exploit this to conduct cross-site request forgery (XSRF) attacks.
(CVE-2014-8638)
Xiaofeng Zheng discovered that a web proxy returning a 407 response
could inject cookies in to the originally requested domain. If a user
connected to a malicious web proxy, an attacker could potentially exploit
this to conduct session-fixation attacks. (CVE-2014-8639)
