CVE-2000-1254
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…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.14%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
