CVSS: 7.5EPSS: 81%CPEs: 444EXPL: 7CVE-2023-44487 – HTTP/2 Rapid Reset Attack Vulnerability
https://notcve.org/view.php?id=CVE-2023-44487
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. El protocolo HTTP/2 permite una denegación de servicio (consumo de recursos del servidor) porque la cancelación de solicitudes puede restablecer muchas transmisiones rápidamente, como se explotó en la naturaleza entre agosto y octubre de 2023. A flaw was found in handling multiplexed streams in the HTTP/2 protocol. A client can repeatedly make a request for a new multiplex stream and immediately send an RST_STREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any server-side limit for the maximum number of active streams per connection, resulting in a denial of service due to server resource consumption. • https://github.com/imabee101/CVE-2023-44487 https://github.com/studiogangster/CVE-2023-44487 https://github.com/bcdannyboy/CVE-2023-44487 https://github.com/sigridou/CVE-2023-44487- https://github.com/ByteHackr/CVE-2023-44487 https://github.com/ReToCode/golang-CVE-2023-44487 http://www.openwall.com/lists/oss-security/2023/10/13/4 http://www.openwall.com/lists/oss-security/2023/10/13/9 http://www.openwall.com/lists/oss-security/2023/10/18/4 http://www. • CWE-400: Uncontrolled Resource Consumption •
CVSS: 8.1EPSS: 0%CPEs: 5EXPL: 0CVE-2023-39323 – Arbitrary code execution during build via line directives in cmd/go
https://notcve.org/view.php?id=CVE-2023-39323
Line directives ("//line") can be used to bypass the restrictions on "//go:cgo_" directives, allowing blocked linker and compiler flags to be passed during compilation. This can result in unexpected execution of arbitrary code when running "go build". The line directive requires the absolute path of the file in which the directive lives, which makes exploiting this issue significantly more complex. Las directivas de línea ("//line") se pueden utilizar para evitar las restricciones de las directivas "//go:cgo_", permitiendo que se pasen indicadores bloqueados del enlazador y del compilador durante la compilación. Esto puede provocar la ejecución inesperada de código arbitrario al ejecutar "go build". • https://go.dev/cl/533215 https://go.dev/issue/63211 https://groups.google.com/g/golang-announce/c/XBa1oHDevAo https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/CLB4TW7KALB3EEQWNWCN7OUIWWVWWCG2 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/KSEGD2IWKNUO3DWY4KQGUQM5BISRWHQE https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/XFOIBB4YFICHDM7IBOP7PWXW3FX4HLL2 https://pkg.go.dev/vuln/GO-2023-2095 https: •

https://notcve.org/view.php?id=CVE-2023-39319
The html/template package does not apply the proper rules for handling occurrences of "<script", "<!--", and "</script" within JS literals in <script> contexts. This may cause the template parser to improperly consider script contexts to be terminated early, causing actions to be improperly escaped. This could be leveraged to perform an XSS attack.

CVSS: 5.3EPSS: 0%CPEs: 5EXPL: 1CVE-2023-29409 – Large RSA keys can cause high CPU usage in crypto/tls
https://notcve.org/view.php?id=CVE-2023-29409
Extremely large RSA keys in certificate chains can cause a client/server to expend significant CPU time verifying signatures. With fix, the size of RSA keys transmitted during handshakes is restricted to <= 8192 bits. Based on a survey of publicly trusted RSA keys, there are currently only three certificates in circulation with keys larger than this, and all three appear to be test certificates that are not actively deployed. It is possible there are larger keys in use in private PKIs, but we target the web PKI, so causing breakage here in the interests of increasing the default safety of users of crypto/tls seems reasonable. A denial of service vulnerability was found in the Golang Go package caused by an uncontrolled resource consumption flaw. • https://github.com/mateusz834/CVE-2023-29409 https://go.dev/cl/515257 https://go.dev/issue/61460 https://groups.google.com/g/golang-announce/c/X0b6CsSAaYI/m/Efv5DbZ9AwAJ https://pkg.go.dev/vuln/GO-2023-1987 https://security.gentoo.org/glsa/202311-09 https://security.netapp.com/advisory/ntap-20230831-0010 https://access.redhat.com/security/cve/CVE-2023-29409 https://bugzilla.redhat.com/show_bug.cgi?id=2228743 • CWE-400: Uncontrolled Resource Consumption •
