Debian DLA-896-1 : icedove/thunderbird security update
Critical Nessus Plugin ID 99442
SynopsisThe remote Debian host is missing a security update.
DescriptionMultiple security issues have been found in the Mozilla Thunderbird mail client: Multiple memory safety errors, buffer overflows and other implementation errors may lead to the execution of arbitrary code or spoofing.
With version 45.8 Debian drops it's custom branding from the Icedove package and ships the mail client as Thunderbird again. Please see the link below for further information:
Transition packages for the Icedove packages are provided which automatically upgrade to the new version. Since new binary packages need to be installed, make sure to allow that in your upgrade procedure (e.g. by using 'apt-get dist-upgrade' instead of 'apt-get upgrade').
For Debian 7 'Wheezy', these problems have been fixed in version 1:45.8.0-3~deb7u1.
We recommend that you upgrade your icedove packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpgrade the affected packages.
