Multiple vulnerabilities were discovered in Enigmail, an OpenPGP extension for Thunderbird, which could result in a loss of confidentiality, faked signatures, plain text leaks and denial of service. Additional information can be found under https://enigmail.net/download/other/Enigmail Pentest Report by%2 0Cure53%20-%20Excerpt.pdf
For Debian 7 ‘Wheezy’, these problems have been fixed in version 2:1.9.9-1~deb7u1.
We recommend that you upgrade your enigmail 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.
