Log Message:
openssl: updated to 1.1.1w
Changes between 1.1.1v and 1.1.1w [11 Sep 2023]
*) 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.
