![]() (CVE-2013-4206)īuffer 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. 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. It is integrated in multiple applications on multiple operating systems for providing SSH, Telnet and Rlogin protocol support.įileZilla Client and WinSCP both use the vulnerable PuTTY code. PuTTY is a client program for the SSH, Telnet and Rlogin network protocols.
