CVE-2023-22485 – cmark-gfm out-of-bounds read in validate_protocol
https://notcve.org/view.php?id=CVE-2023-22485
cmark-gfm is GitHub's fork of cmark, a CommonMark parsing and rendering library and program in C. In versions prior 0.29.0.gfm.7, a crafted markdown document can trigger an out-of-bounds read in the `validate_protocol` function. We believe this bug is harmless in practice, because the out-of-bounds read accesses `malloc` metadata without causing any visible damage.This vulnerability has been patched in 0.29.0.gfm.7. cmmark-gfm es la bifurcación de GitHub de cmark, una librería y programa de análisis y representación de CommonMark en C. En versiones anteriores a la 0.29.0.gfm.7, un documento de rebajas manipulado puede desencadenar una lectura fuera de los límites en la función `validate_protocol` . Creemos que este error es inofensivo en la práctica, porque la lectura fuera de los límites accede a los metadatos "malloc" sin causar ningún daño visible. • https://github.com/github/cmark-gfm/security/advisories/GHSA-c944-cv5f-hpvr • CWE-91: XML Injection (aka Blind XPath Injection) CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2023-22484
cmark-gfm is GitHub's fork of cmark, a CommonMark parsing and rendering library and program in C. Versions prior to 0.29.0.gfm.7 are subject to a polynomial time complexity issue in cmark-gfm that may lead to unbounded resource exhaustion and subsequent denial of service. This vulnerability has been patched in 0.29.0.gfm.7. cmark-gfm es la bifurcación de GitHub de cmark, una librería y programa de análisis y representación de CommonMark en C. Las versiones anteriores a 0.29.0.gfm.7 están sujetas a un problema de complejidad de tiempo polinómico en cmark-gfm que puede provocar un agotamiento ilimitado de los recursos y posterior denegación del servicio. Esta vulnerabilidad ha sido parcheada en 0.29.0.gfm.7. • https://github.com/github/cmark-gfm/security/advisories/GHSA-24f7-9frr-5h2r • CWE-400: Uncontrolled Resource Consumption CWE-407: Inefficient Algorithmic Complexity •
CVE-2023-22483 – cmark-gfm Quadratic complexity bugs may lead to a denial of service
https://notcve.org/view.php?id=CVE-2023-22483
cmark-gfm is GitHub's fork of cmark, a CommonMark parsing and rendering library and program in C. Versions prior to 0.29.0.gfm.7 are subject to several polynomial time complexity issues in cmark-gfm that may lead to unbounded resource exhaustion and subsequent denial of service. Various commands, when piped to cmark-gfm with large values, cause the running time to increase quadratically. These vulnerabilities have been patched in version 0.29.0.gfm.7. cmark-gfm es la bifurcación de GitHub de cmark, una librería y programa de análisis y representación de CommonMark en C. Las versiones anteriores a 0.29.0.gfm.7 están sujetas a varios problemas de complejidad de tiempo polinomial en cmark-gfm que pueden provocar un agotamiento ilimitado de los recursos y posterior denegación del servicio. • https://github.com/github/cmark-gfm/security/advisories/GHSA-29g3-96g3-jg6c • CWE-400: Uncontrolled Resource Consumption CWE-407: Inefficient Algorithmic Complexity •
CVE-2022-23739 – Incorrect authorization check in GitHub Enterprise Server leading to escalation of privileges in GraphQL API requests from GitHub Apps using scoped user-to-server tokens
https://notcve.org/view.php?id=CVE-2022-23739
An incorrect authorization vulnerability was identified in GitHub Enterprise Server, allowing for escalation of privileges in GraphQL API requests from GitHub Apps. This vulnerability allowed an app installed on an organization to gain access to and modify most organization-level resources that are not tied to a repository regardless of granted permissions, such as users and organization-wide projects. Resources associated with repositories were not impacted, such as repository file content, repository-specific projects, issues, or pull requests. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.7.1 and was fixed in versions 3.3.16, 3.4.11, 3.5.8, 3.6.4, 3.7.1. This vulnerability was reported via the GitHub Bug Bounty program. • https://docs.github.com/en/enterprise-server%403.3/admin/release-notes#3.3.16 https://docs.github.com/en/enterprise-server%403.4/admin/release-notes#3.4.11 https://docs.github.com/en/enterprise-server%403.5/admin/release-notes#3.5.8 https://docs.github.com/en/enterprise-server%403.6/admin/release-notes#3.6.4 https://docs.github.com/en/enterprise-server%403.7/admin/release-notes#3.7.1 • CWE-863: Incorrect Authorization •
CVE-2022-46258 – Incorrect Authorization in GitHub Enterprise Server leads to Action Workflow modifications without Workflow Scope
https://notcve.org/view.php?id=CVE-2022-46258
An incorrect authorization vulnerability was identified in GitHub Enterprise Server that allowed a repository-scoped token with read/write access to modify Action Workflow files without a Workflow scope. The Create or Update file contents API should enforce workflow scope. This vulnerability affected all versions of GitHub Enterprise Server prior to version 3.7 and was fixed in versions 3.3.16, 3.4.11, 3.5.8, and 3.6.4. This vulnerability was reported via the GitHub Bug Bounty program. Se identificó una vulnerabilidad de autorización incorrecta en GitHub Enterprise Server que permitía que un token con alcance de repositorio con acceso de lectura/escritura modificara archivos de flujo de trabajo de acción sin un alcance de flujo de trabajo. • https://docs.github.com/en/enterprise-server%403.3/admin/release-notes#3.3.16 https://docs.github.com/en/enterprise-server%403.4/admin/release-notes#3.4.11 https://docs.github.com/en/enterprise-server%403.5/admin/release-notes#3.5.8 https://docs.github.com/en/enterprise-server%403.6/admin/release-notes#3.6.4 • CWE-863: Incorrect Authorization •
