Last modified

CVE-2000-1254 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 3.14% chance of exploitation in the next 30 days.
