Mozilla Thunderbird is a popular open-source email client from the Mozilla project.
A use-after-free bug was discovered in Mozilla Thunderbird handling of SCTP.
A remote attacker could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition.
There is no known workaround at this time.
