Description
This security bulletin contains information about 1 vulnerability.
1) Cryptographic issues (CVE-ID: CVE-2007-6755)
CWE-ID: CWE-310 - Cryptographic Issues
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to decrypt sensitive information.
The vulnerability exists due to the Dual Elliptic Curve Deterministic Random Bit Generation (Dual_EC_DRBG) algorithm contains point Q constants with a possible relationship to certain "skeleton key" values. A remote context-dependent attacker can defeat cryptographic protection mechanisms by leveraging knowledge of those values.
Remediation
Install update from vendor's website.
