Red Hat Security Advisory: OpenShift Container Platform 4.19.0 bug fix and security update

Important

A flaw was found in the x/crypto/ssh go library. Applications and libraries that misuse the ServerConfig.PublicKeyCallback callback may be susceptible to an authorization bypass. For example, an attacker may send public keys A and B and authenticate with A. PublicKeyCallback would be called only twice, first with A and then with B. A vulnerable application may then make authorization decisions based on key B, for which the attacker does not control the private key. The misuse of ServerConfig.PublicKeyCallback may cause an authorization bypass.

CWE-285 - Improper Authorization

A flaw was found in golang.org/x/net/html. This flaw allows an attacker to craft input to the parse functions that would be processed non-linearly with respect to its length, resulting in extremely slow parsing. This issue can cause a denial of service.

CWE-770 - Allocation of Resources Without Limits or Throttling
