| Vetor | AV:N/AC:M/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
OpenSSL versions prior to 0.9.8zc
OpenSSL versions prior to 1.0.0o
OpenSSL versions prior to 1.0.1j
Description
The issue is related to a memory leak in the
tls decrypt ticket function, which can be exploited by remote attackers to cause a denial of service due to excessive memory consumption. This can be achieved by sending a specially crafted session ticket that triggers an integrity-check failure. The estimated number of potentially affected devices and details about real-world incidents are not provided.Recommendations
For OpenSSL versions prior to 0.9.8zc, update to version 0.9.8zc or later.
For OpenSSL versions prior to 1.0.0o, update to version 1.0.0o or later.
For OpenSSL versions prior to 1.0.1j, update to version 1.0.1j or later.
As a temporary workaround, consider restricting access to the
tls decrypt ticket function in the t1 lib.c file until a patch is available.Exploit
