| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2016-04-07 | CVE-2016-2563 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products Stack-based buffer overflow in the SCP command-line utility in PuTTY before 0.67 and KiTTY 0.66.6.3 and earlier allows remote servers to cause a denial of service (stack memory corruption) or execute arbitrary code via a crafted SCP-SINK file-size response to an SCP download request. | 7.5 |
| 2015-12-07 | CVE-2015-5309 | Numeric Errors vulnerability in multiple products Integer overflow in the terminal emulator in PuTTY before 0.66 allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via an ECH (erase characters) escape sequence with a large parameter value, which triggers a buffer underflow. | 4.3 |
| 2015-03-27 | CVE-2015-2157 | Information Exposure vulnerability in multiple products The (1) ssh2_load_userkey and (2) ssh2_save_userkey functions in PuTTY 0.51 through 0.63 do not properly wipe SSH-2 private keys from memory, which allows local users to obtain sensitive information by reading the memory. | 2.1 |
| 2013-08-19 | CVE-2013-4852 | Numeric Errors vulnerability in multiple products Integer overflow in PuTTY 0.62 and earlier, WinSCP before 5.1.6, and other products that use PuTTY allows remote SSH servers to cause a denial of service (crash) and possibly execute arbitrary code in certain applications that use PuTTY via a negative size value in an RSA key signature during the SSH handshake, which triggers a heap-based buffer overflow. | 6.8 |
| 2013-08-19 | CVE-2013-4208 | Information Exposure vulnerability in multiple products 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. | 2.1 |
| 2013-08-19 | CVE-2013-4207 | Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in multiple products 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. | 4.3 |
| 2013-08-19 | CVE-2013-4206 | Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in multiple products 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. | 6.8 |
