It was discovered that constructed ASN.1 types with a recursive definition could exceed the stack, potentially leading to a denial of service.

Details can be found in the upstream advisory:
https://www.openssl.org/news/secadv/20180327.txt

For Debian 7 ‘Wheezy’, these problems have been fixed in version 1.0.1t-1+deb7u4.

We recommend that you upgrade your openssl packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
