Heimdal · Heimdal · CVE-2015-5913
**Name of the Vulnerable Software and Affected Versions**
Heimdal versions prior to 10.11
**Description**
The issue is related to inadequate access control in the Heimdal component of the Mac OS X operating system. It allows a remote attacker to conduct replay attacks against the SMB server by exploiting packet data that represents a Kerberos authenticated request. This could potentially enable the attacker to perform network attacks on the SMB server.
**Recommendations**
For versions prior to 10.11, update to version 10.11 or later to resolve the issue. As a temporary workaround, consider restricting access to the SMB server to minimize the risk of exploitation.
