x86 pv: Insufficient care with non-coherent mappings T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen maintains a type reference count for pages, in addition to a regular reference count. This scheme is used to maintain invariants required for Xen's safety, e.g. PV guests may not have direct writeable access to pagetables; updates need auditing by Xen. Unfortunately, Xen's safety logic doesn't account for CPU-induced cache non-coherency; cases where the CPU can cause the content of the cache to be different to the content in main memory. • http://www.openwall.com/lists/oss-security/2022/06/09/4 http://xenbits.xen.org/xsa/advisory-402.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OH65U6FTTB5MLH5A6Q3TW7KVCGOG4MYI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RKRXZ4LHGCGMOG24ZCEJNY6R2BTS4S2Q https://security.gentoo.org/glsa/202208-23 https://www.debian.org/security/2022/dsa-5184 https://xenbits.xenproject.org/xsa/advisory-402.txt •

https://notcve.org/view.php?id=CVE-2022-31214
A Privilege Context Switching issue was discovered in join.c in Firejail 0.9.68. By crafting a bogus Firejail container that is accepted by the Firejail setuid-root program as a join target, a local attacker can enter an environment in which the Linux user namespace is still the initial user namespace, the NO_NEW_PRIVS prctl is not activated, and the entered mount namespace is under the attacker's control. In this way, the filesystem layout can be adjusted to gain root privileges through execution of available setuid-root binaries such as su or sudo. Se ha detectado un problema de cambio de contexto de privilegios en el archivo join.c en Firejail versión 0.9.68. Al diseñar un contenedor Firejail falso que es aceptado por el programa Firejail setuid-root como objetivo de join, un atacante local puede entrar en un entorno en el que el espacio de nombres de usuario de Linux sigue siendo el espacio de nombres de usuario inicial, el prctl NO_NEW_PRIVS no está activado, y el espacio de nombres de montaje introducido está bajo el control del atacante. • https://firejail.wordpress.com/download-2/release-notes https://lists.debian.org/debian-lts-announce/2022/06/msg00023.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6RZOTZ36RUSL6DOVHITY25ZYKWTG5HN3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KUZZ5M6LIBYRKTKGROXC47TDC3FRTGJF https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SIBEBE3KFINMGJATBQQS7D2VQQ62ZVMF https://security.gentoo.org/glsa/202305-19 h • CWE-269: Improper Privilege Management •

https://notcve.org/view.php?id=CVE-2022-31813
Apache HTTP Server 2.4.53 and earlier may not send the X-Forwarded-* headers to the origin server based on client side Connection header hop-by-hop mechanism. This may be used to bypass IP based authentication on the origin server/application. Apache HTTP Server versiones 2.4.53 y anteriores, no envían los encabezados X-Forwarded-* al servidor de origen basándose en el mecanismo hop-by-hop del encabezado de conexión del lado del cliente. Esto puede usarse para evitar la autenticación basada en la IP en el servidor de origen/aplicación A flaw was found in the mod_proxy module of httpd. The server may remove the X-Forwarded-* headers from a request based on the client-side Connection header hop-by-hop mechanism. • http://www.openwall.com/lists/oss-security/2022/06/08/8 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7QUGG2QZWHTITMABFLVXA4DNYUOTPWYQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YPY2BLEVJWFH34AX77ZJPLD2OOBYR6ND https://security.gentoo.org/glsa/202208-20 https://security.netapp.com/advisory/ntap-20220624-0005 https://access.redhat.com/security/cve/CVE-2022-31813 ht • CWE-345: Insufficient Verification of Data Authenticity CWE-348: Use of Less Trusted Source •
