MySQL vulnerability analysis and mitigation

CVE-2024-7254 is a vulnerability in Protocol Buffers (protobuf) that was discovered and disclosed in September 2024. The vulnerability affects any project that parses untrusted Protocol Buffers data containing nested groups or series of SGROUP tags. When exploited, it can lead to stack overflow conditions by exceeding the stack limit through unbounded recursions (NVD, ASEC).

The vulnerability occurs when parsing nested groups as unknown fields with DiscardUnknownFieldsParser or Java Protobuf Lite parser, or against Protobuf map fields. The issue creates unbounded recursions that can be exploited by an attacker. The vulnerability has been assigned a CVSS v4.0 base score of 8.7 (High) with the vector string CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N. The vulnerability is classified under CWE-20 (Improper Input Validation) (NVD).

Successful exploitation of this vulnerability can lead to Denial of Service (DoS) conditions through stack overflow attacks. The vulnerability affects multiple versions of protobuf-java, protobuf-javalite, protobuf-kotlin, protobuf-kotlin-lite, and JRuby gem com-protobuf packages (ASEC, NetApp).

Fixed versions have been released to address this vulnerability. Users should upgrade to protobuf-java version 3.25.5, 4.27.5, or 4.28.2; protobuf-javalite version 3.25.5, 4.27.5, or 4.28.2; protobuf-kotlin version 3.25.5, 4.27.5, or 4.28.2; protobuf-kotlin-lite version 3.25.5, 4.27.5, or 4.28.2; or JRuby gem com-protobuf version 3.25.5, 4.27.5, or 4.28.2 (ASEC).
