CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2023-24534 – Excessive memory allocation in net/http and net/textproto
https://notcve.org/view.php?id=CVE-2023-24534
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. A flaw was found in Golang Go, where it is vulnerable to a denial of service caused by memory exhaustion in the common function in HTTP and MIME header parsing. • https://go.dev/cl/481994 https://go.dev/issue/58975 https://groups.google.com/g/golang-announce/c/Xdv6JL9ENs8 https://pkg.go.dev/vuln/GO-2023-1704 https://security.gentoo.org/glsa/202311-09 https://security.netapp.com/advisory/ntap-20230526-0007 https://access.redhat.com/security/cve/CVE-2023-24534 https://bugzilla.redhat.com/show_bug.cgi?id=2184483 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2023-24536 – Excessive resource consumption in net/http, net/textproto and mime/multipart
https://notcve.org/view.php?id=CVE-2023-24536
Multipart form parsing can consume large amounts of CPU and memory when processing form inputs containing very large numbers of parts. This stems from several causes: 1. mime/multipart.Reader.ReadForm limits the total memory a parsed multipart form can consume. ReadForm can undercount the amount of memory consumed, leading it to accept larger inputs than intended. 2. Limiting total memory does not account for increased pressure on the garbage collector from large numbers of small allocations in forms with many parts. 3. ReadForm can allocate a large number of short-lived buffers, further increasing pressure on the garbage collector. • https://go.dev/cl/482075 https://go.dev/cl/482076 https://go.dev/cl/482077 https://go.dev/issue/59153 https://groups.google.com/g/golang-announce/c/Xdv6JL9ENs8 https://pkg.go.dev/vuln/GO-2023-1705 https://security.gentoo.org/glsa/202311-09 https://security.netapp.com/advisory/ntap-20230526-0007 https://access.redhat.com/security/cve/CVE-2023-24536 https://bugzilla.redhat.com/show_bug.cgi?id=2184482 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 0CVE-2022-41724 – Panic on large handshake records in crypto/tls
https://notcve.org/view.php?id=CVE-2022-41724
Large handshake records may cause panics in crypto/tls. Both clients and servers may send large TLS handshake records which cause servers and clients, respectively, to panic when attempting to construct responses. This affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable session resumption (by setting Config.ClientSessionCache to a non-nil value), and TLS 1.3 servers which request client certificates (by setting Config.ClientAuth >= RequestClientCert). A flaw was found in Golang Go, where it is vulnerable to a denial of service caused when processing large TLS handshake records. By sending specially-crafted TLS handshake records, a remote, authenticated attacker can cause a denial of service condition. • https://go.dev/cl/468125 https://go.dev/issue/58001 https://groups.google.com/g/golang-announce/c/V0aBFqaFs_E https://pkg.go.dev/vuln/GO-2023-1570 https://security.gentoo.org/glsa/202311-09 https://access.redhat.com/security/cve/CVE-2022-41724 https://bugzilla.redhat.com/show_bug.cgi?id=2178492 • CWE-400: Uncontrolled Resource Consumption •
