EUVDB-ID: #VU6890
Risk: Medium
CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-6891
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionA remote attacker can execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in "asn1_find_node()" function (lib/parser_aux.c) within GnuTLS libtasn1 version 4.10 when processing a specially crafted assignments file via the e.g. asn1Coding utility. A remote attacker can trick the victim into opening a specially crafted file, trigger stack-based buffer overflow and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
Update the affected packages.

CVSSv3.1: 4.8 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-1000654
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input within the _asn1_expand_object_id(p_tree) function when parsing a specially crafted file with asn1Parser binary. An attacker can create a specially crafted file, pass it to the application and consume all available CPU resources on the system.
Update the affected packages.
