From 3.0.0 until 3.3.7, 3.4.5, and 3.5.10, the ReadableByteBuf.readLength() and ReadableByteBuf.readIntLengthEncodedNotNull() methods narrowed the protocol's unsigned 8-byte length-encoded integer to a Java int without checking that the value fit a non-negative integer. Values above Integer.MAX_VALUE could wrap to a negative or unrelated length that downstream allocation and read paths used. A malicious or compromised server, or a machine-in-the-middle attacker, could trigger NegativeArraySizeException, out-of-bounds failures, or oversized allocation behavior in client connection handling. This issue is fixed in versions 3.3.7, 3.4.5, and 3.5.10.","epss":{"date":"2026-11-03","percentile":0.28799,"score":0.00351},"exploits":[],"kev":null,"metrics":[{"score":5.9,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},{"score":5.9,"severity":"medium","source":"NVD: security-advisories@github.com","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1793726285513,"publishedAt":1793307142903,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/mariadb-corporation/mariadb-connector-j/security/advisories/GHSA-797x-p4mc-jwpm"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/30d4a883377a9b7762e02ee2c60d54567032ab99"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/bfd9f5ad666a6f7f5401a5b78f2ac2fbd6df8667"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/dbbadc3e215c47bdb913ddf50739ada09a7f23ea"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.3.7"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.4.5"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.5.10"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/30d4a883377a9b7762e02ee2c60d54567032ab99"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/bfd9f5ad666a6f7f5401a5b78f2ac2fbd6df8667"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/dbbadc3e215c47bdb913ddf50739ada09a7f23ea"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.3.7"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.4.5"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.5.10"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/mariadb-corporation/mariadb-connector-j/security/advisories/GHSA-797x-p4mc-jwpm"},{"source":"OSV / GitHub Security Advisories","tags":["advisory"],"url":"https://github.com/advisories/GHSA-797x-p4mc-jwpm"},{"source":"OSV / GitHub Security Advisories","tags":["osv"],"url":"https://osv.dev/vulnerability/GHSA-797x-p4mc-jwpm"}],"remediation":[{"kind":"fix","source":"OSV GHSA-797x-p4mc-jwpm","text":"org.mariadb.jdbc:mariadb-java-client (Maven): OSV reports a fixed version 3.3.7.
