OSV-2023-197: Global-buffer-overflow in base_C_MessageEncryptInit
A global buffer overflow vulnerability exists in the function base_C_MessageEncryptInit in the p11-kit library. This issue was identified by OSS-Fuzz and results in an out-of-bounds read of 8 bytes. Multiple specific versions of p11-kit, from 0.25.0 through 0.26.4, are affected. No CVSS score or vendor patch information is provided, and no known exploits in the wild have been reported.
AI Analysis
Technical Summary
The p11-kit library contains a global buffer overflow vulnerability in the base_C_MessageEncryptInit function, as reported by OSS-Fuzz (OSV-2023-197). The vulnerability involves an out-of-bounds read of 8 bytes, which occurs during message encryption initialization. Affected versions include multiple releases from 0.25.0 to 0.26.4. No official patch or remediation details are provided in the available data.
Potential Impact
The vulnerability allows reading memory beyond the intended buffer boundaries, which could potentially lead to information disclosure or cause application instability. However, no known exploits in the wild have been reported, and the exact impact depends on how the vulnerable function is used within applications.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should monitor vendor communications and consider applying any updates once released. No specific mitigations are provided in the available data.
