CVE-2021-31566 – libarchive: symbolic links incorrectly followed when changing modes, times, ACL and flags of a file while extracting an archive
https://notcve.org/view.php?id=CVE-2021-31566
An improper link resolution flaw can occur while extracting an archive leading to changing modes, times, access control lists, and flags of a file outside of the archive. 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 gain more privileges in a system. Un fallo de resolución de enlaces inapropiado puede ocurrir mientras es extraído un archivo que conlleva a un cambio de modos, tiempos, listas de control de acceso y flags de un archivo fuera del archivo. Un atacante puede proporcionar un archivo malicioso a un usuario víctima, que desencadenaría este fallo cuando intente extraer el archivo. • https://access.redhat.com/security/cve/CVE-2021-31566 https://bugzilla.redhat.com/show_bug.cgi?id=2024237 https://github.com/libarchive/libarchive/commit/b41daecb5ccb4c8e3b2c53fd6147109fc12c3043 https://github.com/libarchive/libarchive/issues/1566 https://lists.debian.org/debian-lts-announce/2022/11/msg00030.html • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

CVE-2021-3744 – kernel: crypto: ccp - fix resource leaks in ccp_run_aes_gcm_cmd()
https://notcve.org/view.php?id=CVE-2021-3744
A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption). This vulnerability is similar with the older CVE-2019-18808. Se ha encontrado un fallo de pérdida de memoria en el kernel de Linux en la función ccp_run_aes_gcm_cmd() en el archivo drivers/crypto/ccp/ccp-ops.c, que permite a atacantes causar una denegación de servicio (consumo de memoria).

CVE-2020-9490 – httpd: Push diary crash on specifically crafted HTTP/2 header
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') •
