Multiple security issues have been found in Icedove, Debian's version of the Mozilla Thunderbird mail and news client: Multiple memory safety errors, buffer overflows, use-after-frees and other implementation errors may lead to the execution of arbitrary code or denial of service. This update updates Icedove to the ESR31 series of Thunderbird. In addition Enigmail was updated to version 1.7.2-1~deb7u1 to ensure compatibility with the new upstream release.

For the stable distribution (wheezy), these problems have been fixed in version 31.2.0-1~deb7u1. For the unstable distribution (sid), these problems have been fixed in version 31.2.0-1. We recommend that you upgrade your icedove packages.

Icedove is an unbranded Thunderbird mail client suitable for free distribution. It supports different mail accounts (POP, IMAP, Gmail), has an integrated learning Spam filter, and offers easy organization of mails with tagging and virtual folders. Also, more features can be added by installing extensions.
