Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200409-26
(Mozilla, Firefox, Thunderbird, Epiphany: New releases fix vulnerabilities)
Mozilla-based products are vulnerable to multiple security issues. Firstly
routines handling the display of BMP images and VCards contain an integer
overflow and a stack buffer overrun. Specific pages with long links, when
sent using the "Send Page" function, and links with non-ASCII
hostnames could both cause heap buffer overruns.
untrusted script code could read and write to the clipboard, signed scripts
could build confusing grant rights dialog boxes, and when dragged onto
rights of the target frame or window. Finally, Mozilla-based mail clients
(Mozilla and Mozilla Thunderbird) are vulnerable to a heap overflow caused
by invalid POP3 mail server responses.
A possible hacker might be able to run arbitrary code with the rights of the user
running the software by enticing the user to perform one of the following
actions: view a specially-crafted BMP image or VCard, use the "Send
Page" function on a malicious page, follow links with malicious
connect to an untrusted POP3 mail server. A possible hacker could also use a
previously-given rights to request XPI installation rights through
a confusing dialog.
There is no known workaround covering all vulnerabilities.
All users should upgrade to the latest stable version:
# emerge sync
# emerge -pv your-version
# emerge your-version
Network Security Threat Level: Medium
