CVSS: 7.8EPSS: 0%CPEs: 19EXPL: 0CVE-2021-23177 – libarchive: extracting a symlink with ACLs modifies ACLs of target
https://notcve.org/view.php?id=CVE-2021-23177
An improper link resolution flaw while extracting an archive can lead to changing the access control list (ACL) of the target of the link. An attacker may provide a malicious archive to a victim user, who would trigger this flaw when trying to extract the archive. A local attacker may use this flaw to change the ACL of a file on the system and gain more privileges. Un fallo de resolución de enlaces inapropiado mientras es extraído un archivo puede conllevar a un cambio de la lista de control de acceso (ACL) del objetivo del enlace. Un atacante puede proporcionar un archivo malicioso a un usuario víctima, que desencadenaría este fallo cuando intentara extraer el archivo. • https://access.redhat.com/security/cve/CVE-2021-23177 https://bugzilla.redhat.com/show_bug.cgi?id=2024245 https://github.com/libarchive/libarchive/commit/fba4f123cc456d2b2538f811bb831483bf336bad https://github.com/libarchive/libarchive/issues/1565 https://lists.debian.org/debian-lts-announce/2022/11/msg00030.html • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

https://notcve.org/view.php?id=CVE-2020-9490
Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers. Apache HTTP Server versiones 2.4.20 hasta 2.4.43.. Un valor especialmente diseñado para el encabezado "Cache-Digest" en una petición HTTP/2 resultaría en un bloqueo cuando el servidor realmente intenta un PUSH HTTP/2 un recurso mas tarde. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00068.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00071.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00081.html http://packetstormsecurity.com/files/160392/Apache-2.4.43-mod_http2-Memory-Corruption.html https://httpd.apache.org/security/vulnerabilities_24.html#CVE-2020-9490 https://lists.apache.org/thread.html/r06f0d87ebb6d59ed8379633f36f72f5b1f79cadfda72ede0830b42cf%40%3Ccvs.httpd.apache.org%3E https://lists& • CWE-400: Uncontrolled Resource Consumption CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
