|---|---|---|---|---|---|
| CVE-2021-28906 | 1 Cesnet | 1 Libyang | 2022-04-06 | 5.0 MEDIUM | 7.5 HIGH |
| In function read_yin_leaf() in libyang <= v1.0.225, it doesn't check whether the value of retval->ext[r] is NULL. In some cases, it can be NULL, which leads to the operation of retval->ext[r]->flags that results in a crash. | |||||
| CVE-2021-28905 | 1 Cesnet | 1 Libyang | 2022-04-05 | 5.0 MEDIUM | 7.5 HIGH |
| In function lys_node_free() in libyang <= v1.0.225, it asserts that the value of node->module can't be NULL. But in some cases, node->module can be null, which triggers a reachable assertion (CWE-617). | |||||
| CVE-2021-28904 | 1 Cesnet | 1 Libyang | 2022-04-05 | 5.0 MEDIUM | 7.5 HIGH |
| In function ext_get_plugin() in libyang <= v1.0.225, it doesn't check whether the value of revision is NULL. If revision is NULL, the operation of strcmp(revision, ext_plugins[u].revision) will lead to a crash. | |||||
| CVE-2021-28903 | 1 Cesnet | 1 Libyang | 2022-04-05 | 5.0 MEDIUM | 7.5 HIGH |
| A stack overflow in libyang <= v1.0.225 can cause a denial of service through function lyxml_parse_mem(). lyxml_parse_elem() function will be called recursively, which will consume stack space and lead to crash. | |||||
| CVE-2021-28902 | 1 Cesnet | 1 Libyang | 2022-04-05 | 5.0 MEDIUM | 7.5 HIGH |
| In function read_yin_container() in libyang <= v1.0.225, it doesn't check whether the value of retval->ext[r] is NULL. In some cases, it can be NULL, which leads to the operation of retval->ext[r]->flags that results in a crash. | |||||
| CVE-2019-20396 | 1 Cesnet | 1 Libyang | 2021-07-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| A segmentation fault is present in yyparse in libyang before v1.0-r1 due to a malformed pattern statement value during lys_parse_path parsing. | |||||
| CVE-2019-20395 | 1 Cesnet | 1 Libyang | 2020-08-24 | 4.3 MEDIUM | 6.5 MEDIUM |
| A stack consumption issue is present in libyang before v1.0-r1 due to the self-referential union type containing leafrefs. Applications that use libyang to parse untrusted input yang files may crash. | |||||
| CVE-2019-20394 | 1 Cesnet | 1 Libyang | 2020-01-23 | 6.8 MEDIUM | 8.8 HIGH |
| A double-free is present in libyang before v1.0-r3 in the function yyparse() when a type statement in used in a notification statement. Applications that use libyang to parse untrusted input yang files may be vulnerable to this flaw, which would cause a crash or potentially code execution. | |||||
| CVE-2019-20393 | 1 Cesnet | 1 Libyang | 2020-01-23 | 6.8 MEDIUM | 8.8 HIGH |
| A double-free is present in libyang before v1.0-r1 in the function yyparse() when an empty description is used. Applications that use libyang to parse untrusted input yang files may be vulnerable to this flaw, which would cause a crash or potentially code execution. | |||||
| CVE-2019-20392 | 1 Cesnet | 1 Libyang | 2020-01-23 | 4.3 MEDIUM | 6.5 MEDIUM |
| An invalid memory access flaw is present in libyang before v1.0-r1 in the function resolve_feature_value() when an if-feature statement is used inside a list key node, and the feature used is not defined. Applications that use libyang to parse untrusted input yang files may crash. | |||||
| CVE-2019-20397 | 1 Cesnet | 1 Libyang | 2020-01-23 | 6.8 MEDIUM | 8.8 HIGH |
| A double-free is present in libyang before v1.0-r1 in the function yyparse() when an organization field is not terminated. Applications that use libyang to parse untrusted input yang files may be vulnerable to this flaw, which would cause a crash or potentially code execution. | |||||
| CVE-2019-20391 | 1 Cesnet | 1 Libyang | 2020-01-23 | 4.3 MEDIUM | 6.5 MEDIUM |
| An invalid memory access flaw is present in libyang before v1.0-r3 in the function resolve_feature_value() when an if-feature statement is used inside a bit. Applications that use libyang to parse untrusted input yang files may crash. | |||||
| CVE-2019-20398 | 1 Cesnet | 1 Libyang | 2020-01-23 | 4.3 MEDIUM | 6.5 MEDIUM |
| A NULL pointer dereference is present in libyang before v1.0-r3 in the function lys_extension_instances_free() due to a copy of unresolved extensions in lys_restr_dup(). Applications that use libyang to parse untrusted input yang files may crash. | |||||
| CVE-2019-19334 | 3 Cesnet, Fedoraproject, Redhat | 3 Libyang, Fedora, Enterprise Linux | 2019-12-18 | 7.5 HIGH | 9.8 CRITICAL |
| In all versions of libyang before 1.0-r5, a stack-based buffer overflow was discovered in the way libyang parses YANG files with a leaf of type "identityref". An application that uses libyang to parse untrusted YANG files may be vulnerable to this flaw, which would allow an attacker to cause a denial of service or possibly gain code execution. | |||||
| CVE-2019-19333 | 2 Cesnet, Redhat | 2 Libyang, Enterprise Linux | 2019-12-17 | 7.5 HIGH | 9.8 CRITICAL |
| In all versions of libyang before 1.0-r5, a stack-based buffer overflow was discovered in the way libyang parses YANG files with a leaf of type "bits". An application that uses libyang to parse untrusted YANG files may be vulnerable to this flaw, which would allow an attacker to cause a denial of service or possibly gain code execution. | |||||
