UBUNTU-CVE-2013-4852

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 S...

Use after free

The rsaverify 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-2013-4852

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 S...

Heap overflow

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...

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 differe...

CVE-2013-4206

PuTTY before 0.63 is affected by CVE-2013-4206 due to a heap-based buffer underflow in modmul (sshbn.c). The vulnerability allows remote SSH servers to cause a denial of service (crash) and possibly memory corruption or code execution via a crafted DSA signature, related to improper handling duri...

CVE-2013-4207

PuTTY before 0.63 is affected by CVE-2013-4207 due to a heap-based buffer overflow in sshbn.c (modular arithmetic during DSA signature handling). The overflow can crash a remote SSH server and is triggered by an invalid DSA signature during the bignum division-by-zero path. This is distinct from ...

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 differe...

CVE-2013-4208

CVE-2013-4208 affects PuTTY up to version 0.63 where rsa_verify mishandles sensitive memory and does not free certain structures, potentially exposing private RSA/DSA keys. Several advisories note updates that merge PuTTY fixes into downstream projects (e.g., FileZilla 3.7.3 and Fedora/OpenSUSE a...
