Local privilege escalation in SafeNet Authentication Client SACSrv

A local privilege escalation vulnerability in Thales SafeNet Authentication Client (SAC) SACSrv can allow an authenticated, non-administrator local user to trigger a heap-based buffer overflow through the service interface. Successful exploitation may allow arbitrary code execution with Local System privileges.This issue affects SAC releases up to and including 10.9 R3 GA (build 10.9.7449).

Privileged file deletion in SafeNet Authentication Client SACSrv

A time-of-check to time-of-use race condition in the SafeNet Authentication Client (SAC) SACSrv log-cleanup function can allow an authenticated, non-administrator local user to redirect a privileged file deletion operation outside the intended log directory.  This issue affects SAC releases up to and including 10.9 R3 GA (build 10.9.7449).

Stack-based buffer overflow in SafeNet Authentication Client SIS token engine

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).

Privilege Escalation in SafeNet Authentication Client

A flaw in Thales SafeNet Authentication Client prior to 10.8 R10 on Windows allows an attacker to execute code at a SYSTEM level via local access.

Privilege Escalation in SafeNet Authentication Client Installer

A flaw in the Windows Installer in Thales SafeNet Authentication Client prior to 10.8 R10 on Windows allows an attacker to escalate their privilege level via local access.

Thales Safenet Authentication Client (SAC) for Linux and Windows through 10.7.7 creates insecure temporary hid and lock files allowing a local attacker, through a symlink attack, to overwrite arbitrary files, and potentially achieve arbitrary command execution with high privileges.
