Описание
Ollama 0.11.5-rc0 through current version 0.13.5 contain a null pointer dereference vulnerability in the multi-modal model image processing functionality. When processing base64-encoded image data via the /api/chat endpoint, the application fails to validate that the decoded data represents valid media before passing it to the mtmd_helper_bitmap_init_from_buf function. This function can return NULL for malformed input, but the code does not check this return value before dereferencing the pointer in subsequent operations. A remote attacker can exploit this by sending specially crafted base64 image data that decodes to invalid media, causing a segmentation fault and crashing the runner process. This results in a denial of service condition where the model becomes unavailable to all users until the service is restarted.
A flaw was found in Ollama's multi-modal model image processing functionality. A remote attacker can exploit this by sending specially crafted base64-encoded image data to the /api/chat endpoint. This malformed input can lead to a null pointer dereference, causing a segmentation fault and crashing the runner process. This results in a denial of service (DoS) condition, making the model unavailable until the service is restarted.
Отчет
This vulnerability is rated Important for Red Hat because Ollama, when processing specially crafted base64-encoded image data via the /api/chat endpoint, is susceptible to a null pointer dereference. This flaw can be exploited by a remote attacker, leading to a denial of service condition where the model becomes unavailable until the service is restarted.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
