CVSS: 8.8EPSS: 1%CPEs: 5EXPL: 0CVE-2023-43655 – Remote Code Execution via web-accessible composer.phar
https://notcve.org/view.php?id=CVE-2023-43655
Composer is a dependency manager for PHP. Users publishing a composer.phar to a public web-accessible server where the composer.phar can be executed as a php file may be subject to a remote code execution vulnerability if PHP also has `register_argc_argv` enabled in php.ini. Versions 2.6.4, 2.2.22 and 1.10.27 patch this vulnerability. Users are advised to upgrade. Users unable to upgrade should make sure `register_argc_argv` is disabled in php.ini, and avoid publishing composer.phar to the web as this is not best practice. • https://github.com/composer/composer/commit/4fce14795aba98e40b6c4f5047305aba17a6120d https://github.com/composer/composer/commit/955a48e6319c8962e5cd421b07c00ab3c728968c https://github.com/composer/composer/commit/95e091c921037b7b6564942845e7b738f6b95c9c https://github.com/composer/composer/security/advisories/GHSA-jm6m-4632-36hf https://lists.debian.org/debian-lts-announce/2024/03/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/66H2WKFUO255T3BZTL72TNYJYH2XM5FG https://lists.fedoraproject.org/arch • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
CVSS: 8.2EPSS: 0%CPEs: 3EXPL: 0CVE-2023-39191 – Kernel: ebpf: insufficient stack type checks in dynptr
https://notcve.org/view.php?id=CVE-2023-39191
An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to executing them. This may allow an attacker with CAP_BPF privileges to escalate privileges and execute arbitrary code in the context of the kernel. Se encontró una falla de validación de entrada incorrecta en el subsistema eBPF del kernel de Linux. El problema se debe a una falta de validación adecuada de los punteros dinámicos dentro de los programas eBPF proporcionados por el usuario antes de ejecutarlos. • https://access.redhat.com/errata/RHSA-2023:6583 https://access.redhat.com/errata/RHSA-2024:0381 https://access.redhat.com/errata/RHSA-2024:0439 https://access.redhat.com/errata/RHSA-2024:0448 https://access.redhat.com/security/cve/CVE-2023-39191 https://bugzilla.redhat.com/show_bug.cgi?id=2226783 https://www.zerodayinitiative.com/advisories/ZDI-CAN-19399 • CWE-20: Improper Input Validation •

A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds read by setting the size fields with a value beyond the array boundaries, leading to a crash or information disclosure.

A flaw was found in the XFRM subsystem in the Linux kernel. The specific flaw exists within the processing of state filters, which can result in a read past the end of an allocated buffer. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, potentially leading to an information disclosure.
