CVE-2023-26917 1 Cesnet 1 Libyang 2024-11-21 7.5 High
libyang from v2.0.164 to v2.1.30 was discovered to contain a NULL pointer dereference via the function lysp_stmt_validate_value at lys_parse_mem.c.
CVE-2023-26916 2 Cesnet, Fedoraproject 2 Libyang, Fedora 2024-11-21 5.3 Medium
libyang from v2.0.164 to v2.1.30 was discovered to contain a NULL pointer dereference via the function lys_parse_mem at lys_parse_mem.c.
CVE-2021-28906 1 Cesnet 1 Libyang 2024-11-21 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 2024-11-21 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 2024-11-21 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 2024-11-21 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 2024-11-21 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-2019-20398 2 Cesnet, Redhat 2 Libyang, Enterprise Linux 2024-11-21 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-2019-20397 2 Cesnet, Redhat 2 Libyang, Enterprise Linux 2024-11-21 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-2019-20396 2 Cesnet, Redhat 2 Libyang, Enterprise Linux 2024-11-21 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 2 Cesnet, Redhat 2 Libyang, Enterprise Linux 2024-11-21 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 2 Cesnet, Redhat 2 Libyang, Enterprise Linux 2024-11-21 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 2 Cesnet, Redhat 2 Libyang, Enterprise Linux 2024-11-21 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 2 Cesnet, Redhat 2 Libyang, Enterprise Linux 2024-11-21 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-2019-20391 2 Cesnet, Redhat 2 Libyang, Enterprise Linux 2024-11-21 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-2019-19334 3 Cesnet, Fedoraproject, Redhat 3 Libyang, Fedora, Enterprise Linux 2024-11-21 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 2024-11-21 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.
