CVE-2000-1254: OpenSSL

High severity, CVSS 7.5. EPSS: 3.1% chance of exploitation in the next 30 days.

crypto/rsa/rsa_gen.c in OpenSSL before 0.9.6 mishandles C bitwise-shift operations that exceed the size of an expression, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by leveraging improper RSA key generation on 64-bit HP-UX platforms.

Affected products

• OpenSSL OpenSSL: up to and including 0.9.5
