TOP VULNERABILITY THIS WEEK: Microsoft Releases Emergency Out-of-Band

Patch for Remote Code Execution Vulnerability


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Microsoft Releases Emergency Out-of-Band Patch for Remote Code
Execution Vulnerability
Description: Microsoft has released an emergency out-of-band patch
addressing a remote code execution vulnerability (CVE-2015-2426) within
the Adobe Type Manager Library (ATMFD). The vulnerability is due to the
way ATMFD fails to handle OpenType fonts properly. This vulnerability
has been found within the Hacking Team information dump.
Reference: https://technet.microsoft.com/en-us/library/security/MS15-078
Snort SID: 35304-35305

Title: OpenSSH Keyboard-Interactive Authentication Brute Force
Vulnerability (MaxAuthTries bypass)
Description: A brute-force vulnerability has been disclosed that could
allow an attacker to request as many password prompt as possible under
a limited “login graced time” setting. By default, most system have
keyboard-interactive authentication enabled by default along with a
login grace time of two minutes. This vulnerability can be abused such
that an attacker can, for example, attempt 10,000 password entries at a
time per grace period if no additional mitigations are in place. A
public working proof of concept exists for this vulnerability.
