A buffer overflow was found in bogofilter’s character set conversion handling. Certain invalid UTF-8 character sequences caused an invalid memory access. By sending a specially crafted email, a remote attacker could exploit this to crash bogofilter or possibly even execute arbitrary code with bogofilter’s privileges.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
