DEBIAN-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...

Buffer overflow

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 differe...
