openssl-1_1/openssl-1_1-fips-drbg-selftest.patch
Pedro Monreal Gonzalez 8f01c56ec8 Accepting request 1111331 from home:ohollmann:branches:security:tls 
- Update to 1.1.1w:
 * Fix POLY1305 MAC implementation corrupting XMM registers on Windows.
   The POLY1305 MAC (message authentication code) implementation in OpenSSL
   does not save the contents of non-volatile XMM registers on Windows 64
   platform when calculating the MAC of data larger than 64 bytes. Before
   returning to the caller all the XMM registers are set to zero rather than
   restoring their previous content. The vulnerable code is used only on newer
   x86_64 processors supporting the AVX512-IFMA instructions.
   The consequences of this kind of internal application state corruption can
   be various - from no consequences, if the calling application does not
   depend on the contents of non-volatile XMM registers at all, to the worst
   consequences, where the attacker could get complete control of the
   application process. However given the contents of the registers are just
   zeroized so the attacker cannot put arbitrary values inside, the most likely
   consequence, if any, would be an incorrect result of some application
   dependent calculations or a crash leading to a denial of service.
   (CVE-2023-4807)
