Ollama downloadBlob Improper Validation of Array Index Denial-of-Service Vulnerability. This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Ollama. Authentication is not required to exploit this vulnerability. The specific flaw exists within the downloadBlob function. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated array. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-27277.

A flaw was found in Ollama. This vulnerability allows remote attackers to create a denial-of-service (DoS) condition on affected installations. The issue occurs within the downloadBlob function due to improper validation of user-supplied data, which can lead to memory access beyond the bounds of an allocated array.
