Severity: High Date : 2017-06-02 CVE-ID : CVE-2017-6891 Package : libtasn1 Type : arbitrary code execution Remote : Yes Link : https://security.archlinux.org/AVG-285
The package libtasn1 before version 4.11-1 is vulnerable to arbitrary code execution.
Upgrade to 4.11-1.
The problem has been fixed upstream in version 4.11.
Two errors in the "asn1_find_node()" function (lib/parser_aux.c) within GnuTLS libtasn1 version 4.10 can be exploited to cause a stacked-based buffer overflow by tricking a user into processing a specially crafted assignments file via the e.g. asn1Coding utility.
A remote attacker can execute arbitrary code on the affected host by tricking a local user into processing a specially crafted assignments file.
