Title
Stack-based buffer overflow in SafeNet Authentication Client SIS token engine
Summary
A stack-based buffer overflow in Thales SafeNet Authentication Client (SAC) SIS token engine processing can be triggered by a malicious physical or software-emulated smart card. The issue can occur before authentication or PIN entry and may
cause a denial of service or potentially arbitrary code execution with the privileges of the affected process. Affected releases start with SAC 10.8 R7 and include SAC 10.9 R3 GA (build 10.9.7449).

Title
Unauthenticated Stack Buffer Overflow in Sentinel Keys Server
Summary
Stack-based buffer overflow and missing
authorization vulnerability in Thales Sentinel Keys Server on Windows allows
Overflow Buffers. Sentinel Keys Server does not check the length of the first
field in the HTTP request. An attacker may craft an HTTP request and send it to
Sentinel Keys Server. It may lead to remote code execution as NT
AUTHORITY\SYSTEM.
This issue affects Sentinel Keys Server:
versions lower than 1.3.8.0.
