"According to the versions of the shim packages installed, the EulerOS installation on the remote host is affected by the
following vulnerabilities :
- Issue summary: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or
parameters may be very slow. Impact summary: Applications that use the functions DH_generate_key() to
generate an X9.42 DH key may experience long delays. Likewise, applications that use DH_check_pub_key(),
DH_check_pub_key_ex() or EVP_PKEY_public_check() to check an X9.42 DH key or X9.42 DH parameters may
experience long delays. Where the key or parameters that are being checked have been obtained from an
untrusted source this may lead to a Denial of Service. While DH_check() performs all the necessary checks
(as of CVE-2023-3817), DH_check_pub_key() doesn't make any of these checks, and is therefore vulnerable
for excessively large P and Q parameters. Likewise, while DH_generate_key() performs a check for an
excessively large P, it doesn't check for an excessively large Q. An application that calls
DH_generate_key() or DH_check_pub_key() and supplies a key or parameters obtained from an untrusted source
could be vulnerable to a Denial of Service attack. DH_generate_key() and DH_check_pub_key() are also
called by a number of other OpenSSL functions. An application calling any of those other functions may
similarly be affected. The other functions affected by this are DH_check_pub_key_ex(),
EVP_PKEY_public_check(), and EVP_PKEY_generate(). Also vulnerable are the OpenSSL pkey command line
application when using the '-pubcheck' option, as well as the OpenSSL genpkey command line application.
The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers
are not affected by this issue. (CVE-2023-5678)
