x86 pv: Race condition in typeref acquisition 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, the logic for acquiring a type reference has a race condition, whereby a safely TLB flush is issued too early and creates a window where the guest can re-establish the read/write mapping before writeability is prohibited.

Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.53 and prior versions.

In Apache HTTP Server 2.4.53 and earlier, a malicious request to a lua script that calls r:parsebody(0) may cause a denial of service due to no default limit on possible input size.

Apache HTTP Server 2.4.53 and earlier may return lengths to applications calling r:wsread() that point past the end of the storage allocated for the buffer.

The ap_rwrite() function in Apache HTTP Server 2.4.53 and earlier may read unintended memory if an attacker can cause the server to reflect very large input using ap_rwrite() or ap_rputs(), such as with mod_luas r:puts() function.

Gogs is an open source self-hosted Git service. In versions of gogs prior to 0.12.9 `DisplayName` does not filter characters input from users, which leads to an XSS vulnerability when directly displayed in the issue list. This issue has been resolved in commit 155cae1d which sanitizes `DisplayName` prior to display to the user. All users of gogs are advised to upgrade. Users unable to upgrade should check their users' display names for malicious characters.

Apache HTTP Server 2.4.53 and earlier on Windows may read beyond bounds when configured to process requests with the mod_isapi module.

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.

An Insecure Direct Object Reference (IDOR) issue in fn2Web in ihb eG FlexNow before 2.04.09.016 allows remote authenticated attackers to obtain sensitive student information (final grades, study courses, degrees) by changing the student ID parameter in the HTTP POST request to the FrontControllerSS endpoint.

At a 2022 RSA Conference keynote, technologist Bruce Schneier asserted that artificial intelligence agents will start to hack human systems — and what that will mean for us.
