Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Null pointer dereference
EUVDB-ID: #VU10322
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-10790
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the _asn1_check_identifier function in GNU Libtasn1 due to insufficient validation of user-supplied input. A remote attacker can submit a specially crafted input, trigger assignment of a NULL value within an asn1_node structure and cause the service to crash.
Update the affected package to version: 4.10-1.1+deb9u1
Vulnerable software versionsDebian Linux: All versions

2) Resource exhaustion
EUVDB-ID: #VU10323
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-6003
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the _asn1_decode_simple_ber function in decoding.c in GNU Libtasn1. A remote attacker can trigger unlimited recursion in the BER decoder and stack exhaustion to cause the service to crash.
