Description Bernard Cafarelli gentoo-dev 2013-08-27 13:54:21 UTC
After CVE-2013-4852 (bug #479880), a series of vulnerabilities was found and fixed in filezilla 3.7.3 (available in tree)
Comment 1 GLSAMaker/CVETool Bot gentoo-dev 2013-08-28 14:03:35 UTC
CVE-2013-4208 (
  The rsa_verify function in PuTTY before 0.63 (1) does not clear sensitive
  process memory after use and (2) does not free certain structures containing
  sensitive process memory, which might allow local users to discover private
  RSA and DSA keys.

CVE-2013-4207 (
  Buffer overflow in sshbn.c in PuTTY before 0.63 allows remote SSH servers to
  cause a denial of service (crash) via an invalid DSA signature that is not
  properly handled during computation of a modular inverse and triggers the
  overflow during a division by zero by the bignum functionality, a different
  vulnerability than CVE-2013-4206.

CVE-2013-4206 (
  Heap-based buffer underflow in the modmul function in sshbn.c in PuTTY
  before 0.63 allows remote SSH servers to cause a denial of service (crash)
  and possibly trigger memory corruption or code execution via a crafted DSA
  signature, which is not properly handled when performing certain
  bit-shifting operations during modular multiplication.
