Integer Underflow (Wrap or Wraparound)

Overview Affected versions of this package are vulnerable to Integer Underflow Wrap or Wraparound via the sslDecodePacket process. An attacker can cause a program crash and trigger a large out-of-bounds read by injecting a malformed TLS Application Data record that is shorter than the required...

PT-2026-29789

Name of the Vulnerable Software and Affected Versions Mbed TLS versions 3.0 through 3.6.5 Description An out-of-bounds read issue exists in the mbedtls ccm finish function within the library/ccm.c file of Mbed TLS. This allows attackers to potentially obtain adjacent CCM context data by invoking...

Inadequate Encryption Strength

github.com/cloudflare/gokey is vulnerable to Inadequate Encryption Strength. The vulnerability is due to flawed seed decryption logic that uses only limited entropy from the initialization vector and authentication tag, which allows an attacker with access to the seed file to derive generated...
