### Overview A flaw in Jackson-core's `JsonLocation._appendSourceDesc` method allows up to 500 bytes of unintended memory content to be included in exception messages. When parsing JSON from a byte array with an offset and length, the exception message incorrectly reads from the beginning of the array instead of the logical payload start. This results in possible **information disclosure** in systems using **pooled or reused buffers**, like Netty or Vert.x. ### Details The vulnerability affects the creation of exception messages like: ``` JsonParseException: Unexpected character ... at [Source: (byte[])...] ``` When `JsonFactory.createParser(byte[] data, int offset, int len)` is used, and an error occurs while parsing, the exception message should include a snippet from the specified logical payload. However, the method `_appendSourceDesc` ignores the `offset`, and always starts reading from index `0`. If the buffer contains residual sensitive data from a previous request, such a...
### Impact On schemas involving arrows with caveats on the arrow’ed relation, when the path to resolve a CheckPermission request involves the evaluation of multiple caveated branches, requests may return a negative response when a positive response is expected. For example, given this schema: ``` definition user {} definition office { relation parent: office relation manager: user permission read = manager + parent->read } definition group { relation parent: office permission read = parent->read } definition document { relation owner: group with equals permission read = owner->read } caveat equals(actual string, required string) { actual == required } ``` and these relationships: ``` office:headoffice#manager@user:maria office:branch1#parent@office:headoffice group:admins#parent@office:branch1 group:managers#parent@office:headoffice document:budget#owner@group:admins[equals:{"required":"admin"}] document:budget#owner@group:managers[equals:{"required":"manager"}] ``` P...
### Summary A **Denial of Service (DoS)** vulnerability was discovered in the CoreDNS DNS-over-QUIC (DoQ) server implementation. The server previously created a new goroutine for every incoming QUIC stream without imposing any limits on the number of concurrent streams or goroutines. A remote, unauthenticated attacker could open a large number of streams, leading to uncontrolled memory consumption and eventually causing an Out Of Memory (OOM) crash — especially in containerized or memory-constrained environments. ### Impact - **Component**: `server_quic.go` - **Attack Vector**: Remote, network-based - **Attack Complexity**: Low - **Privileges Required**: None - **User Interaction**: None - **Impact**: High availability loss (OOM kill or unresponsiveness) This issue affects deployments with `quic://` enabled in the Corefile. A single attacker can cause the CoreDNS instance to become unresponsive using minimal bandwidth and CPU. ### Patches The patch introduces two key mitigation m...
In an effort to evade detection, cybercriminals are increasingly turning to “residential proxy” services that cover their tracks by making it look like everyday online activity.
Popular Chrome extensions exposed user data by sending it over unencrypted HTTP, raising privacy concerns. Symantec urges caution for users.
**Overview** The laravel-auth0 SDK contains a critical vulnerability due to insecure deserialization of cookie data. If exploited, since SDKs process cookie content without prior authentication, a threat actor could send a specially crafted cookie containing malicious serialized data. **Am I Affected?** You are affected by this vulnerability if you meet the following preconditions: 1. Applications using laravel-auth0 SDK, versions between 7.0.0-BETA1 to 7.2.1. 2. Laravel-auth0 SDK uses the Auth0-PHP SDK with version 8.0.0-BETA3 to 8.3.0. **Fix** Upgrade Auth0/laravel-auth0 to the latest version (v7.17.0). **Acknowledgement** Okta would like to thank Andreas Forsblom for discovering this vulnerability.
