libyang is a YANG data modeling language library. Prior to SO 5.2.15, lybreadstring() in src/parserlyb.c contains an integer overflow that results in a heap buffer overflow when parsing a maliciously crafted LYB binary blob. An attacker who can supply LYB data to any libyang consumer (NETCONF server, sysrepo, etc.) can trigger a crash or potential heap corruption. This vulnerability is fixed in SO 5.2.15.

libyang from v2.0.164 to v2.1.30 was discovered to contain a NULL pointer dereference via the function lyspstmtvalidatevalue at lysparsemem.c.

A vulnerability has been found in CESNET theme-cesnet up to 1.x on ownCloud and classified as problematic. Affected by this vulnerability is an unknown functionality of the file cesnet/core/lostpassword/templates/resetpassword.php. The manipulation leads to insufficiently protected credentials. Attacking locally is a requirement. Upgrading to version 2.0.0 is able to address this issue. The identifier of the patch is 2b857f2233ce5083b4d5bc9bfc4152f933c3e4a6. It is recommended to upgrade the affected component. The identifier VDB-217633 was assigned to this vulnerability.
In function readyinleaf() 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.
In function lysnodefree() 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).
In function extgetplugin() 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, extplugins[u].revision) will lead to a crash.
A stack overflow in libyang <= v1.0.225 can cause a denial of service through function lyxmlparsemem(). lyxmlparseelem() function will be called recursively, which will consume stack space and lead to crash.
In function readyincontainer() 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.
In Perun before version 3.9.1, VO or group manager can modify configuration of the LDAP extSource to retrieve all from Perun LDAP. Issue is fixed in version 3.9.1 by sanitisation of the input.
An invalid memory access flaw is present in libyang before v1.0-r1 in the function resolvefeaturevalue() 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.
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.
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.
A NULL pointer dereference is present in libyang before v1.0-r3 in the function lysextensioninstancesfree() due to a copy of unresolved extensions in lysrestrdup(). Applications that use libyang to parse untrusted input yang files may crash.
An invalid memory access flaw is present in libyang before v1.0-r3 in the function resolvefeaturevalue() when an if-feature statement is used inside a bit. Applications that use libyang to parse untrusted input yang files may crash.
A segmentation fault is present in yyparse in libyang before v1.0-r1 due to a malformed pattern statement value during lysparsepath parsing.
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.
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.
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.
