An attacker can trigger a denial of service via a `CHECK`-fail in `tf.raw_ops.CTCGreedyDecoder`. This is because the implementation(https://github.com/tensorflow/tensorflow/blob/1615440b17b364b875eb06f43d087381f1460a65/tensorflow/core/kernels/ctc_decoder_ops.cc#L37-L50) has a `CHECK_LT` inserted to validate some invariants. When this condition is false, the program aborts, instead of returning a valid error to the user. This abnormal termination can be weaponized in denial of service attacks. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2021-29543","url":"https://www.suse.com/security/cve/CVE-2021-29543"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1186108 for CVE-2021-29543","url":"https://bugzilla.suse.com/1186108"}],"title":"SUSE CVE CVE-2021-29543","tracking":{"current_release_date":"2025-02-17T05:32:30Z","generator":{"date":"2023-02-15T03:43:18Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2021-29543","initial_release_date":"2023-02-15T03:43:18Z","revision_history":[{"date":"2023-02-15T03:43:18Z","number":"2","summary":"Current version"},{"date":"2025-01-01T04:35:17Z","number":"3","summary":"Current version"},{"date":"2025-02-15T05:09:40Z","number":"4","summary":"Current version"},{"date":"2025-02-17T05:32:30Z","number":"5","summary":"Current version"}],"status":"interim","version":"5"}}}
