| In the Linux kernel, the following vulnerability has been resolved:
x86/xen: Drop USERGS_SYSRET64 paravirt call
commit afd30525a659ac0ae0904f0cb4a2ca75522c3123 upstream.
USERGS_SYSRET64 is used to return from a syscall via SYSRET, but
a Xen PV guest will nevertheless use the IRET hypercall, as there
is no sysret PV hypercall defined.
So instead of testing all the prerequisites for doing a sysret and
then mangling the stack for Xen PV again for doing an iret just use
the iret exit from the beginning.
This can easily be done via an ALTERNATIVE like it is done for the
sysenter compat case already.
It should be noted that this drops the optimization in Xen for not
restoring a few registers when returning to user mode, but it seems
as if the saved instructions in the kernel more than compensate for
this drop (a kernel build in a Xen PV guest was slightly faster with
this patch applied).
While at it remove the stale sysret32 remnants.
[ pawan: Brad Spengler and Salvatore Bonaccorso <carnil@debian.org>
reported a problem with the 5.10 backport commit edc702b4a820
("x86/entry_64: Add VERW just before userspace transition").
When CONFIG_PARAVIRT_XXL=y, CLEAR_CPU_BUFFERS is not executed in
syscall_return_via_sysret path as USERGS_SYSRET64 is runtime
patched to:
.cpu_usergs_sysret64 = { 0x0f, 0x01, 0xf8,
0x48, 0x0f, 0x07 }, // swapgs; sysretq
which is missing CLEAR_CPU_BUFFERS. It turns out dropping
USERGS_SYSRET64 simplifies the code, allowing CLEAR_CPU_BUFFERS
to be explicitly added to syscall_return_via_sysret path. Below
is with CONFIG_PARAVIRT_XXL=y and this patch applied:
syscall_return_via_sysret:
...
<+342>: swapgs
<+345>: xchg %ax,%ax
<+347>: verw -0x1a2(%rip) <------
<+354>: sysretq

| Code Injection in GitHub repository froxlor/froxlor prior to 0.10.39. |
| Spring Tools 4 for Eclipse version 4.16.0 and below as well as VSCode extensions such as Spring Boot Tools, Concourse CI Pipeline Editor, Bosh Editor and Cloudfoundry Manifest YML Support version 1.39.0 and below all use Snakeyaml library for YAML editing support. This library allows for some special syntax in the YAML that under certain circumstances allows for potentially harmful remote code execution by the attacker. |
| SAP GUI allows an authenticated attacker to execute scripts in the local network. On successful exploitation, the attacker can gain access to registries which can cause a limited impact on confidentiality and high impact on availability of the application.

| In Splunk Enterprise versions below 8.2.9, 8.1.12, and 9.0.2, an authenticated user can execute arbitrary code through the dashboard PDF generation component.

| The Import any XML or CSV File to WordPress plugin before 3.6.9 is not properly filtering which file extensions are allowed to be imported on the server, which could allow administrators in multi-site WordPress installations to upload arbitrary files |
| In Splunk Enterprise versions below 8.2.9, 8.1.12, and 9.0.2, sending a malformed file through the Splunk-to-Splunk (S2S) or HTTP Event Collector (HEC) protocols to an indexer results in a blockage or denial-of-service preventing further indexing.

| Server-Side Request Forgery (SSRF) vulnerability in Hitachi Infrastructure Analytics Advisor on Linux (Data Center Analytics, Analytics probe components), Hitachi Ops Center Analyzer on Linux (Hitachi Ops Center Analyzer detail view, Hitachi Ops Center Analyzer probe components) allows Server Side Request Forgery.
This issue affects Hitachi Infrastructure Analytics Advisor: from 2.0.0-00 through 4.4.0-00; Hitachi Ops Center Analyzer: from 10.0.0-00 before 10.9.0-00.

| In isp, there is a possible out of bounds write due to uninitialized data. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07341258; Issue ID: ALPS07341258. |

| A flaw was found in moodle. When creating an export of site administration presets, some sensitive secrets and keys are not being excluded from the export, which could result in them unintentionally being leaked if the presets are shared with a third party. |
| A flaw was found in Moodle. Additional restrictions are required to avoid a remote code execution risk in calculated question types. Note: This requires the capability to add/update questions. |
| An HTTP Request Forgery issue was discovered in Varnish Cache 5.x and 6.x before 6.0.11, 7.x before 7.1.2, and 7.2.x before 7.2.1. An attacker may introduce characters through HTTP/2 pseudo-headers that are invalid in the context of an HTTP/1 request line, causing the Varnish server to produce invalid HTTP/1 requests to the backend. This could, in turn, be used to exploit vulnerabilities in a server behind the Varnish server. Note: the 6.0.x LTS series (before 6.0.11) is affected. |
| The Chat activity in Moodle 4.3.3 allows students to insert a potentially unwanted HTML A element or IMG element, or HTML content that leads to a performance degradation. NOTE: the vendor's Using_Chat page says "If you know some HTML code, you can use it in your text to do things like insert images, play sounds or create different coloured and sized text." This page also says "Chat is due to be removed from standard Moodle." |
| Improperly Controlled Modification of Dynamically-Determined Object Attributes vulnerability in Drupal Drupal core allows Object Injection.This issue affects Drupal core: from 8.0.0 before 10.3.13, from 10.4.0 before 10.4.3, from 11.0.0 before 11.0.12, from 11.1.0 before 11.1.3. |
| In Emacs before 29.3, arbitrary Lisp code is evaluated as part of turning on Org mode. This affects Org Mode before 9.6.23. |
| ESPCMS P8.21120101 was discovered to contain a remote code execution (RCE) vulnerability in the component IS_GETCACHE. |
