CVE-2013-4207 (GCVE-0-2013-4207)
Vulnerability from cvelistv5 – Published: 2013-08-19 23:00 – Updated: 2024-08-06 16:38
VLAI
Summary
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.
Severity
No CVSS data available.

Summary
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.

CVE-2013-4852 (GCVE-0-2013-4852)
Vulnerability from cvelistv5 – Published: 2013-08-19 23:00 – Updated: 2024-08-06 16:59
VLAI
Summary
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.
Severity
No CVSS data available.
