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: •
CVSS: 6.1EPSS: 0%CPEs: 2EXPL: 0CVE-2023-39319 – Improper handling of special tags within script contexts in html/template
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.

The html/template package does not properly handle HTML-like "" comment tokens, nor hashbang "#!" comment tokens, in <script> contexts.

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 •
CVSS: 6.5EPSS: 0%CPEs: 2EXPL: 0CVE-2023-29406 – Insufficient sanitization of Host header in net/http
https://notcve.org/view.php?id=CVE-2023-29406
The HTTP/1 client does not fully validate the contents of the Host header. A maliciously crafted Host header can inject additional headers or entire requests. With fix, the HTTP/1 client now refuses to send requests containing an invalid Request.Host or Request.URL.Host value. A flaw was found in Golang, where it is vulnerable to HTTP header injection caused by improper content validation of the Host header by the HTTP/1 client. A remote attacker can inject arbitrary HTTP headers by persuading a victim to visit a specially crafted Web page. • https://go.dev/cl/506996 https://go.dev/issue/60374 https://groups.google.com/g/golang-announce/c/2q13H6LEEx0 https://pkg.go.dev/vuln/GO-2023-1878 https://security.gentoo.org/glsa/202311-09 https://security.netapp.com/advisory/ntap-20230814-0002 https://access.redhat.com/security/cve/CVE-2023-29406 https://bugzilla.redhat.com/show_bug.cgi?id=2222167 • CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') CWE-436: Interpretation Conflict •
