Adam discovered several problems in inspircd, an IRC daemon:
An incomplete patch for CVE-2012-1836
failed to adequately resolve the problem where maliciously crafted DNS
requests could lead to remote code execution through a heap-based buffer
overflow.
The incorrect processing of specific DNS packets could trigger an
infinite loop, thus resulting in a denial of service.
