Vulnerabilities for 'LDNS'

2022-01-21

CVE-2020-19861

CWE-120

When a zone file in ldns 1.7.1 is parsed, the function ldns_nsec3_salt_data is too trusted for the length value obtained from the zone file. When the memcpy is copied, the 0xfe - ldns_rdf_size(salt_rdf) byte data can be copied, causing heap overflow information leakage.

CVE-2020-19860

CWE-125

When ldns version 1.7.1 verifies a zone file, the ldns_rr_new_frm_str_internal function has a heap out of bounds read vulnerability. An attacker can leak information on the heap by constructing a zone file payload.

CVE-2017-1000232

CWE-415

A double-free vulnerability in str2host.c in ldns 1.7.0 have unspecified impact and attack vectors.

CVE-2017-1000231

CWE-415

A double-free vulnerability in parse.c in ldns 1.7.0 have unspecified impact and attack vectors.

2014-11-15

CVE-2014-3209

CWE-264

The ldns-keygen tool in ldns 1.6.x uses the current umask to set the privileges of the private key, which might allow local users to obtain the private key by reading the file.

2011-11-04

CVE-2011-3581

Heap-based buffer overflow in the ldns_rr_new_frm_str_internal function in ldns before 1.6.11 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a Resource Record (RR) with an unknown type containing input that is longer than a specified length.

2009-03-25

CVE-2009-1086

CWE-399

Heap-based buffer overflow in the ldns_rr_new_frm_str_internal function in ldns 1.4.x allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code via a DNS resource record (RR) with a long (1) class field (clas variable) and possibly (2) TTL field.
