Security update for openssl-3

This update for openssl-3 fixes the following issues:

  • CVE-2024-6119: Fixed denial of service in X.509 name checks (bsc#1229465)

Other fixes:

  • FIPS: Deny SHA-1 signature verification in FIPS provider (bsc#1221365).
  • FIPS: RSA keygen PCT requirements.
  • FIPS: Check that the fips provider is available before setting it as the default provider in FIPS mode (bsc#1220523).
  • FIPS: Port openssl to use jitterentropy (bsc#1220523).
  • FIPS: Block non-Approved Elliptic Curves (bsc#1221786).
  • FIPS: Service Level Indicator (bsc#1221365).
  • FIPS: Output the FIPS-validation name and module version which uniquely identify the FIPS validated module (bsc#1221751).
  • FIPS: Add required selftests: (bsc#1221760).
  • FIPS: DH: Disable FIPS 186-4 Domain Parameters (bsc#1221821).
  • FIPS: Recommendation for Password-Based Key Derivation (bsc#1221827).
  • FIPS: Zero initialization required (bsc#1221752).
  • FIPS: Reseed DRBG (bsc#1220690, bsc#1220693, bsc#1220696).
  • FIPS: NIST SP 800-56Brev2 (bsc#1221824).
  • FIPS: Approved Modulus Sizes for RSA Digital Signature for FIPS 186-4 (bsc#1221787).
  • FIPS: Port openssl to use jitterentropy (bsc#1220523).
  • FIPS: NIST SP 800-56Arev3 (bsc#1221822).
  • FIPS: Error state has to be enforced (bsc#1221753).

Issue summary: Applications performing certificate name checks (e.g., TLS clients checking server certificates) may attempt to read an invalid memory address resulting in abnormal termination of the application process. Impact summary: Abnormal termination of an application can a cause a denial of service. Applications performing certificate name checks (e.g., TLS clients checking server certificates) may attempt to read an invalid memory address when comparing the expected name with an `otherName` subject alternative name of an X.509 certificate. This may result in an exception that terminates the application program. Note that basic certificate chain validation (signatures, dates, ...) is not affected, the denial of service can occur only when the application also specifies an expected DNS name, Email address or IP address. TLS servers rarely solicit client certificates, and even when they do, they generally don't perform a name check against a reference identifier (expected identity), but rather extract the presented identity after checking the certificate chain. So TLS servers are generally not affected and the severity of the issue is Moderate. The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.
