Where:

From remote

Impact:

Spoofing, Exposure of sensitive information, DoS, System access

Solution Status:

Vendor Patch

CVE Reference(s):

Description


The vendor has released details about some older vulnerabilities in Mozilla, Mozilla Firefox, and Thunderbird. These can potentially be exploited by malicious people to conduct spoofing attacks, compromise a vulnerable system, or cause a DoS (Denial of Service).

1) Malicious POP3 mail servers can cause an heap overflow in Mozilla and obtain system access.

2) A malicious page can appear to be encrypted and present the certificate of another site.

3) Mozilla doesn't verify if stored credentials should be used for a HTTPS or HTTP connection. This can potentially lead to the password being sent over an unencrypted HTTP connection.

4) Certificate name matching is done insecurely for non-FQDNs (Fully Qualified Domain Name), which may be used for spoofing attacks.

5) Malicious websites can interfere with the operations in other windows and cause a DoS. However, it is not possible to alter or read any data.

6) Users can be tricked into dragging text into obscured file upload controls, resulting in theft of a local file from a known location.

7) The PNG library (libpng) contains an out-of-bounds read vulnerability, which can be exploited by malicious people to cause a DoS.

Some other older issues were also reported.

These vulnerabilities reportedly affect versions prior to the following:
* Mozilla 1.7
* Firefox 0.9
* Thunderbird 0.7

NOTE: These issues have all been fixed by the vendor. However, the details have not been disclosed earlier.


Solution:
The vulnerabilities have reportedly been fixed in:
