Synopsis

The remote Debian host is missing a security update.

Description

CVE-2017-10790 The _asn1_check_identifier function in GNU Libtasn1 through 4.12 causes a NULL pointer dereference and crash when reading crafted input that triggers assignment of a NULL value within an asn1_node structure. It may lead to a remote denial of service attack.

For Debian 7 'Wheezy', these problems have been fixed in version 2.13-2+deb7u5.

We recommend that you upgrade your libtasn1-3 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.

Solution

Upgrade the affected packages.
