[GLSA-200701-03] Mozilla Thunderbird: Multiple vulnerabilities Vulnerability Scan

Vulnerability Scan Summary
Mozilla Thunderbird: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200701-03
(Mozilla Thunderbird: Multiple vulnerabilities)

Georgi Guninski and David Bienvenu discovered buffer overflows in the
processing of long "Content-Type:" and long non-ASCII MIME headers.
Additionally, Frederik Reiss discovered a heap-based buffer overflow in
the conversion of a CSS cursor. Different vulnerabilities involving
memory corruption in the browser engine were also fixed. Mozilla
Thunderbird also contains less severe vulnerabilities involving
JavaScript and Java.


A possible hacker could entice a user to view a specially crafted email that
will trigger one of these vulnerabilities, possibly leading to the
execution of arbitrary code. A possible hacker could also perform cross-site
scripting attacks, leading to the exposure of sensitive information,
like user credentials. Note that the execution of JavaScript or Java
applets is disabled by default and enabling it is strongly discouraged.


There are no known workarounds for all the issues at this time.


All Mozilla Thunderbird users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-"
All Mozilla Thunderbird binary release users should upgrade to the
latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-bin-"

Threat Level: High
