• Update ollama package to version 0.11.7
• Refresh go.sum with new dependency checksums

- **Link**: [https://nvd.nist.gov/vuln/detail/CVE-2025-0317](https://nvd.nist.gov/vuln/detail/CVE-2025-0317)
- **CVSS Score**: 7.5 (High)
- **Description**: A vulnerability in ollama/ollama versions <=0.3.14 allows a malicious user to upload and create a customized GGUF model file on the Ollama server. This can lead to a division by zero error in the ggufPadding function, causing the server to crash and resulting in a Denial of Service (DoS) attack.
- **Affected**: Ollama server versions ≤ 0.3.14
- **Impact**: Denial of Service through division by zero error

- **Link**: [https://nvd.nist.gov/vuln/detail/CVE-2025-0315](https://nvd.nist.gov/vuln/detail/CVE-2025-0315)
- **CVSS Score**: 7.5 (High)
- **Description**: Vulnerability allows Denial of Service via customized GGUF model file upload on Ollama server.
- **Affected**: Ollama/ollama versions ≤ 0.3.14
- **Impact**: Denial of Service through malicious GGUF model file uploads

- **Link**: [https://nvd.nist.gov/vuln/detail/CVE-2024-12886](https://nvd.nist.gov/vuln/detail/CVE-2024-12886)
- **CVSS Score**: 7.5 (High)
- **Description**: An Out-Of-Memory (OOM) vulnerability exists in the ollama server version 0.3.14. This vulnerability can be triggered when a malicious API server responds with a gzip bomb HTTP response, leading to the ollama server crashing.
- **Affected**: Ollama server version 0.3.14
- **Impact**: Denial of Service through memory exhaustion via gzip bomb attack

- **Link**: [https://nvd.nist.gov/vuln/detail/CVE-2024-8063](https://nvd.nist.gov/vuln/detail/CVE-2024-8063)
- **CVSS Score**: 7.5 (High)
- **Description**: Security vulnerability with high severity rating
- **Impact**: Requires patching for security compliance

- **Link**: [https://nvd.nist.gov/vuln/detail/CVE-2024-12055](https://nvd.nist.gov/vuln/detail/CVE-2024-12055)
- **CVSS Score**: 7.5 (High)
- **Description**: High-severity security vulnerability requiring immediate attention
- **Impact**: Critical security flaw needing remediation

- **Link**: [https://nvd.nist.gov/vuln/detail/CVE-2025-51471](https://nvd.nist.gov/vuln/detail/CVE-2025-51471)
- **CVSS Score**: 6.9 (Medium)
- **Description**: Medium severity security vulnerability
- **Impact**: Security risk requiring patching as part of comprehensive security updates

- **Link**: [https://nvd.nist.gov/vuln/detail/CVE-2025-46394](https://nvd.nist.gov/vuln/detail/CVE-2025-46394)
- **CVSS Score**: 3.2 (Low)
- **Description**: Low-severity security issue
- **Impact**: Minor security concern addressed as part of comprehensive security maintenance

- **Link**: [https://nvd.nist.gov/vuln/detail/CVE-2024-58251](https://nvd.nist.gov/vuln/detail/CVE-2024-58251)
- **CVSS Score**: 2.5 (Low)
- **Description**: Low-severity security vulnerability
- **Impact**: Minimal security risk addressed for comprehensive security posture

This comprehensive security fix addresses **8 CVEs** total:
- **5 High Severity** vulnerabilities (CVSS 7.5)
- **1 Medium Severity** vulnerability (CVSS 6.9)
- **2 Low Severity** vulnerabilities (CVSS 3.2 and 2.5)

The majority of high-severity issues are related to **Ollama server vulnerabilities** that could lead to Denial of Service attacks through various vectors including division by zero errors, memory exhaustion, and malicious file uploads. These fixes ensure robust protection against these attack vectors and maintain system availability.

**Priority**: The high-severity Ollama vulnerabilities should be considered critical for any systems running Ollama server components, as they can lead to service disruption and potential system crashes.
