When a slash is the first meaningful token, with the start of input or only whitespace and comments before it, there is no valid preceding token: the walk back over whitespace and comment nodes runs off the head of the node list to NULL, and the byte lookup reads through a NULL contents pointer at an underflowed length index. The following identifier check dereferences the same NULL pointer.\n\nThe crash is reachable through the public minify() API, so input as small as a single slash byte crashes the calling process. A service that minifies untrusted or third-party JavaScript can be crashed by a remote request, causing denial of service."

Later, this inconsistency leads to a NULL pointer dereference and an eventual crash.

Versions 3.4.0 through 3.4.12 contain a NULL pointer dereference in the OpenEXRCore function exr_attr_set_bytes(). The public setter validates the top-level exr_attr_bytes_t value pointer but does not verify that the nested type_hint pointer is non-NULL when hint_length is greater than zero. When a caller supplies a positive hint_length together with a NULL type_hint, exr_attr_bytes_create() allocates a destination type-hint buffer and then copies from the NULL source pointer, causing a deterministic crash. The flaw is reachable through the public OpenEXRCore C API and results in a denial of service. The issue is fixed in version 3.4.13."

In versions 4.0.0 through 4.14.6, a malicious or man-in-the-middle enrollment manager can crash a Wazuh agent during enrollment by returning a malformed key response with fewer than four fields, causing a NULL pointer dereference. The \u00a0w_enrollment_process_agent_key()\u00a0 routine splits the manager-provided key into four space-separated fields but does not verify that all fields are present before passing them to validators. Because OS_StrBreak() leaves missing trailing entries as NULL and OS_IsValidName() calls strlen() on its argument without a NULL check, a response such as \u00a0OSSEC K:\u00271\u0027\u00a0 reaches OS_IsValidName(NULL) and terminates the agent process. Since Wazuh permits enrollment against an unverified manager when no CA certificate is configured, an attacker operating a rogue manager or intercepting the enrollment flow can deterministically crash agents, resulting in denial of service. This issue is fixed in version 4.14.7."

Versions 1.7.14 through 1.7.17 are vulnerable to a nil-pointer panic triggered by a protobuf Transaction whose embedded RawData sub-message is omitted. This omission causes RawData to decode to nil. Every transaction gossiped on the Klever-Go P2P network is decoded and validated synchronously inside the libp2p pubsub topic-validator callback, where txVersionChecker.CheckTxVersion dereferences tx.RawData.Version with no nil check. Because the libp2p pubsub callback, the underlying go-libp2p-pubsub validation worker, and Klever\u0027s own network/p2p layer install no recover(), the panic propagates and crashes the entire node process. The attacker payload is a 3-byte protobuf message; no validator key, stake, funds, or on-chain account is required, and delivery aimed at enough of the BLS validator set can halt block production, resulting in a chain halt. This issue has been fixed in version 1.7.18."
