Red Hat Security Advisory: capstone security update
Two security vulnerabilities have been identified in the Capstone disassembly framework used in Red Hat Enterprise Linux 10 and related products. The first is a memory corruption issue caused by an unchecked vsnprintf return (CVE-2025-68114). The second is a heap buffer overflow triggered via the skipdata callback, which can lead to denial of service or arbitrary code execution (CVE-2025-67873). Red Hat has released an important security update addressing these issues for multiple architectures and variants of Red Hat Enterprise Linux 10 and CodeReady Linux Builder 10.
AI Analysis
Technical Summary
Capstone, a disassembly framework used for binary analysis and reversing, has two reported vulnerabilities: CVE-2025-68114 involves memory corruption due to an unchecked vsnprintf return, and CVE-2025-67873 involves a heap buffer overflow via the skipdata callback that can cause denial of service or arbitrary code execution. Red Hat has issued security advisories and released updated RPM packages (capstone-5.0.7-0.1.hum1 and related packages) for Red Hat Hardened Images to address these vulnerabilities. The advisories do not provide CVSS scores but classify the severity as high. No known exploits in the wild have been reported. The vendor advisory confirms the availability of fixes and directs users to apply the updates.
Potential Impact
The heap buffer overflow vulnerability (CVE-2025-67873) can lead to denial of service or arbitrary code execution, which poses a significant security risk. The memory corruption vulnerability (CVE-2025-68114) also impacts stability and security. Both vulnerabilities affect the Capstone framework within Red Hat Hardened Images, potentially compromising systems that use these components if left unpatched.
Mitigation Recommendations
Red Hat has released updated RPM packages for Capstone version 5.0.7-0.1.hum1 that address these vulnerabilities. Users of Red Hat Hardened Images should apply these official updates promptly. No additional mitigation steps are indicated by the vendor advisory. Patch status is confirmed by the vendor advisory.
