Security Fix(es):
|
|
|
|
A security vulnerability has been identified in all supported versions
|
|
|
|
of OpenSSL related to the verification of X.509 certificate chains
|
|
that include policy constraints. Attackers may be able to exploit this
|
|
vulnerability by creating a malicious certificate chain that triggers
|
|
exponential use of computational resources, leading to a denial-of-service
|
|
(DoS) attack on affected systems.
|
|
|
|
Policy processing is disabled by default but can be enabled by passing
|
|
the `-policy' argument to the command line utilities or by calling the
|
|
`X509_VERIFY_PARAM_set1_policies()' function.(CVE-2023-0464)</Note>
|
|
<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for shim is now available for openEuler-22.03-LTS-SP2.
