Vulnerable: < 0.8.8-r1
Unaffected: >= 0.8.8-r1
Architectures: All supported architectures

• Uli Schlachter reported that bip does not properly handle invalid
  data during authentication, resulting in a daemon crash
  (CVE-2010-3071).

  file descriptors against FD_SETSIZE, resulting in a stack buffer
  overflow (CVE-2012-0806).
  

Impact
