Detailsinfo

A vulnerability was found in Net Textproro on Go (version now known). It has been declared as problematic. This vulnerability affects some unknown processing. The manipulation with an unknown input leads to a resource consumption vulnerability. The CWE definition for the vulnerability is CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. As an impact it is known to affect availability. CVE summarizes:

HTTP and MIME header parsing can allocate large amounts of memory, even when parsing small inputs, potentially leading to a denial of service. Certain unusual patterns of input data can cause the common function used to parse HTTP and MIME headers to allocate substantially more memory than required to hold the parsed headers. An attacker can exploit this behavior to cause an HTTP server to allocate large amounts of memory from a small request, potentially leading to memory exhaustion and a denial of service. With fix, header parsing now correctly allocates only the memory required to hold parsed headers.

The weakness was released 04/07/2023. The advisory is shared for download at go.dev. This vulnerability was named CVE-2023-24534 since 01/25/2023. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1499.
