  script_tag(name:"insight", value:"Multiple flaws exist due to:

  - An 'authfile.c' script does not properly consider the effects of realloc on buffer contents.

  - The shared memory manager (associated with pre-authentication compression) does not ensure that
  a bounds check is enforced by all compilers.

  - The sshd in OpenSSH creates forwarded Unix-domain sockets as root, when privilege separation is
  not used.

  - An untrusted search path vulnerability in ssh-agent.c in ssh-agent.

  - NULL pointer dereference error due to an out-of-sequence NEWKEYS message.");

  sensitive private-key information, to gain privileges, conduct a senial-of-service condition and
