+
+ *) 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.

+ Changes between 1.1.1u and 1.1.1v [1 Aug 2023]
+
+ *) Fix excessive time spent checking DH q parameter value.
+
+ The function DH_check() performs various checks on DH parameters. After
+ fixing CVE-2023-3446 it was discovered that a large q parameter value can
+ also trigger an overly long computation during some of these checks.
+ A correct q value, if present, cannot be larger than the modulus p
+ parameter, thus it is unnecessary to perform these checks if q is larger
+ than p.
+
+ If DH_check() is called with such q parameter value,
+ DH_CHECK_INVALID_Q_VALUE return flag is set and the computationally
+ intensive checks are skipped.

+
+ *) Fix DH_check() excessive time with over sized modulus
+
+ The function DH_check() performs various checks on DH parameters. One of
+ those checks confirms that the modulus ("p" parameter) is not too large.
+ Trying to use a very large modulus is slow and OpenSSL will not normally use
+ a modulus which is over 10,000 bits in length.
+
+ However the DH_check() function checks numerous aspects of the key or
+ parameters that have been supplied. Some of those checks use the supplied
+ modulus value even if it has already been found to be too large.
+
+ A new limit has been added to DH_check of 32,768 bits. Supplying a
+ key/parameters with a modulus over this size will simply cause DH_check()
+ to fail.
