Two potential buffer overflow vulnerabilities at the following locations in the Zephyr eS-WiFi driver source code.

snappy-java is a Java port of the snappy, a fast C++ compresser/decompresser developed by Google. The SnappyInputStream was found to be vulnerable to Denial of Service (DoS) attacks when decompressing data with a too large chunk size. Due to missing upper bound check on chunk length, an unrecoverable fatal error can occur. All versions of snappy-java including the latest released version 1.1.10.3 are vulnerable to this issue. A fix has been introduced in commit `9f8c3cf74` which will be included in the 1.1.10.4 release. Users are advised to upgrade. Users unable to upgrade should only accept compressed data from trusted sources.

A reflected cross-site scripting (XSS) vulnerability was found in the 'oob' OAuth endpoint due to incorrect null-byte handling. This issue allows a malicious link to insert an arbitrary URI into a Keycloak error page. This flaw requires a user or administrator to interact with a link in order to be vulnerable. This may compromise user details, allowing it to be changed or collected by an attacker.

### Summary snappy-java is a data compression library in Java. Its SnappyInputStream was found to be vulnerable to Denial of Service (DoS) attacks when decompressing data with a too-large chunk size. Due to missing upper bound check on chunk length, an unrecoverable fatal error can occur. ### Scope All versions of snappy-java including the latest released version 1.1.10.3.
