CVE-2010-5298: Race condition in the ssl3_read_bytes function in s3_pkt.c in OpenSSL through 1.0.1g, when SSL_MODE_RELEASE...

Security readout for executives and security teams

This is an OpenSSL race condition that can affect some multithreaded SSL/TLS services. Under the documented configuration, a remote attacker could cause denial of service or mix injected data across sessions. The source bundle does not show active exploitation or a CVSS score. Exposure is most likely in legacy applications, appliances, or packaged products using OpenSSL through 1.0.1g with SSL_MODE_RELEASE_BUFFERS enabled and multithreaded SSL handling. The bundle lists multiple downstream advisories but does not provide complete affected product/version mapping. Handle as a targeted legacy exposure check, not an emergency. Prioritize externally reachable systems and vendor-managed appliances that still depend on old OpenSSL builds. Mitigation focus: Identify systems using OpenSSL through 1.0.1g.; Apply vendor updates that explicitly address CVE-2010-5298.; Check product advisories from appliance and software vendors..
