- 7.1 High severity
golang.org/x/crypto/ssh: Incorrect Authorization
Previously, CVE-2024-45337 fixed an authorization bypass for misused ssh server configurations; if any other type of callback is passed other than public key, then the source-address validation would be skipped.
- 7.4 High severity
golang.org/x/crypto/ssh/knownhosts: Improper Certificate Validation
Previously, a revoked 'SignatureKey' belonging to a CA was not correctly checked for revocation. Now, both the 'key' and 'key.SignatureKey' are checked for @revoked.
- 7.5 High severity
golang.org/x/crypto/ssh: Improper Certificate Validation
SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate. CertChecker now returns an error instead of panicking when these callbacks are nil.
- 8.7 High severity
golang.org/x/crypto/ssh/agent: Deserialization of Untrusted Data
When adding a key to a remote agent constraint extensions such as [email protected] were not serialized in the request. Destination restrictions were silently stripped when forwarding keys, allowing unrestricted use of the key on the remote
- 7.5 High severity
golang.org/x/crypto/ssh: Improper Restriction of Operations within the Bounds of a Memory Buffer
A malicious SSH peer could send unsolicited global request responses to fill an internal buffer, blocking the connection's read loop. The blocked goroutine could not be released by calling Close(), resulting in a resource leak per connection. Unsolicited globa
- 7.5 High severity
golang.org/x/crypto/ssh: Improper Verification of Cryptographic Signature
The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by u
- 8.8 High severity
golang.org/x/crypto/ssh: Improper Certificate Validation
When an SSH server authentication callback returned PartialSuccessError with non-nil Permissions, those permissions were silently discarded, potentially dropping certificate restrictions such as force-command after a second factor succeeded. Returning non-nil
- 7.5 High severity
golang.org/x/net/http2: Loop with Unreachable Exit Condition
When processing HTTP/2 SETTINGS frames, transport will enter an infinite loop of writing CONTINUATION frames if it receives a SETTINGS_MAX_FRAME_SIZE with a value of 0.
- 8.1 High severity
contour: Improper Control of Generation of Code
Contour is a Kubernetes ingress controller using Envoy proxy. From v1.19.0 to before v1.33.4, v1.32.5, and v1.31.6, Contour's Cookie Rewriting feature is vulnerable to Lua code injection. An attacker with RBAC permissions to create or modify HTTPProxy resource
- 8.2 High severity
crypto/x509: Improper Certificate Validation
When verifying a certificate chain containing excluded DNS constraints, these constraints are not correctly applied to wildcard DNS SANs which use a different case than the constraint. This only affects validation of otherwise trusted certificate chains, issue
- 7.5 High severity
istio: Exposure of Sensitive Information to an Unauthorized Actor
Istio is an open platform to connect, manage, and secure microservices. Prior to 1.29.1, 1.28.5, and 1.27.8, a user of Istio is impacted if the JWKS resolver becomes unavailable or the fetch fails, exposing hardcoded defaults regardless of use of the RequestAu
- 7.5 High severity
crypto/x509: Improper Certificate Validation
When verifying a certificate chain which contains a certificate containing multiple email address constraints which share common local portions but different domain portions, these constraints will not be properly applied, and only the last constraint will be
