CWE: CWE-400
Description: A regular expression denial of service (ReDoS) vulnerability was found in nodejs-ansi-regex. This could possibly cause an application using ansi-regex to use an excessive amount of CPU time when matching crafted ANSI escape codes.
Statement: This flaw requires crafted invalid ANSI escape codes in order to be exploited and only allows for denial of service of applications on the client side, hence the impact has been rated as Moderate.

In Red Hat Virtualization and Red Hat Quay some components use a vulnerable version of ansi-regex. However, all frontend code is executed on the client side. As the maximum impact of this vulnerability is denial of service in the client, the vulnerability is rated Moderate for those products.

OpenShift Container Platform 4 (OCP) ships affected version of ansi-regex in the ose-metering-hadoop container, however the metering operator is deprecated since 4.6[1]. This issue is not currently planned to be addressed in future updates and hence hadoop container has been marked as 'will not fix'.

Advanced Cluster Management for Kubernetes (RHACM) ships the affected version of ansi-regex in several containers, however the impact of this vulnerability is deemed low as it would result in an authenticated slowing down their own user interface.

Description: In the Linux kernel, the following vulnerability has been resolved:

ethtool: strset: fix message length calculation

Outer nest for ETHTOOL_A_STRSET_STRINGSETS is not accounted for.
This may result in ETHTOOL_MSG_STRSET_GET producing a warning like:

    calculated message payload length (684) not sufficient
    WARNING: CPU: 0 PID: 30967 at net/ethtool/netlink.c:369 ethnl_default_doit+0x87a/0xa20

and a splat.

As usually with such warnings three conditions must be met for the warning
to trigger:
 - there must be no skb size rounding up (e.g. reply_size of 684);
 - string set must be per-device (so that the header gets populated);
 - the device name must be at least 12 characters long.

all in all with current user space it looks like reading priv flags
is the only place this could potentially happen. Or with syzbot :)

Description: In the Linux kernel, the following vulnerability has been resolved:

tcp: fix tcp_init_transfer() to not reset icsk_ca_initialized

This commit fixes a bug (found by syzkaller) that could cause spurious
double-initializations for congestion control modules, which could cause
memory leaks or other problems for congestion control modules (like CDG)
that allocate memory in their init functions.

The buggy scenario constructed by syzkaller was something like:

(1) create a TCP socket
(2) initiate a TFO connect via sendto()
(3) while socket is in TCP_SYN_SENT, call setsockopt(TCP_CONGESTION),
    which calls:
       tcp_set_congestion_control() ->
         tcp_reinit_congestion_control() ->
           tcp_init_congestion_control()
(4) receive ACK, connection is established, call tcp_init_transfer(),
    set icsk_ca_initialized=0 (without first calling cc->release()),
    call tcp_init_congestion_control() again.

Note that in this sequence tcp_init_congestion_control() is called
twice without a cc->release() call in between. Thus, for CC modules
that allocate memory in their init() function, e.g, CDG, a memory leak
may occur. The syzkaller tool managed to find a reproducer that
triggered such a leak in CDG.

The bug was introduced when that commit 8919a9b31eb4 ("tcp: Only init
congestion control if not initialized already")
introduced icsk_ca_initialized and set icsk_ca_initialized to 0 in
tcp_init_transfer(), missing the possibility for a sequence like the
one above, where a process could call setsockopt(TCP_CONGESTION) in
state TCP_SYN_SENT (i.e. after the connect() or TFO open sendmsg()),
which would call tcp_init_congestion_control(). It did not intend to
reset any initialization that the user had already explicitly made;
it just missed the possibility of that particular sequence (which
syzkaller managed to find).

Description: In DCE/RPC it is possible to share the handles (cookies for resource state) between multiple connections via a mechanism called 'association groups'. These handles can reference connections to our sam.ldb database. However while the database was correctly shared, the user credentials state was only pointed at, and when one connection within that association group ended, the database would be left pointing at an invalid 'struct session_info'. The most likely outcome here is a crash, but it is possible that the use-after-free could instead allow different user state to be pointed at and this might allow more privileged access.

Description: In the Linux kernel, the following vulnerability has been resolved:

arm64: dts: qcom: msm8998: Fix CPU/L2 idle state latency and residency

The entry/exit latency and minimum residency in state for the idle
states of MSM8998 were ..bad: first of all, for all of them the
timings were written for CPU sleep but the min-residency-us param
was miscalculated (supposedly, while porting this from downstream);
Then, the power collapse states are setting PC on both the CPU
cluster *and* the L2 cache, which have different timings: in the
specific case of L2 the times are higher so these ones should be
taken into account instead of the CPU ones.

This parameter misconfiguration was not giving particular issues
because on MSM8998 there was no CPU scaling at all, so cluster/L2
power collapse was rarely (if ever) hit.
When CPU scaling is enabled, though, the wrong timings will produce
SoC unstability shown to the user as random, apparently error-less,
sudden reboots and/or lockups.

This set of parameters are stabilizing the SoC when CPU scaling is
ON and when power collapse is frequently hit.

CWE: CWE-94
Description: A flaw was found in nodejs-handlebars. A unescaped value in the JavaScriptCompiler.prototype.depthedLookup function allows an attacker, who can provide untrusted handlebars templates, to execute arbitrary code in the javascript system (e.g. browser or server) when the template is compiled with the compat:true option. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
Statement: Red Hat OpenShift Container Platform (OCP) 4 delivers the kibana component which includes Handlebars.js.  Starting in 4.6, kibana is shipping as "container first" content.  As such, the fix for OCP will be seen in the affected products table under openshift4/ose-logging-kibana6.  The separate package "kibana" listed under "OpenShift Container Platform 4" is only used by 4.5 and earlier and will not be fixed.

In OpenShift Container Platform (OCP) and OpenShift ServiceMesh (OSSM) some components include the vulnerable handlebars library, but access is protected by OpenShift OAuth what reducing impact by this flaw to LOW.

Red Hat Quay includes Handlebars.js as a development dependency. It does not use Handlebars.js at runtime to process templates so have been given a low impact rating.

Red Hat Gluster Storage 3 bundles vulnerable Handlebars.js (with pcs), however it does not use "compat" option and templates from external sources, hence this issue has been rated as having a security impact of Low.

Currently collapse_file does not explicitly check PG_writeback, instead,
page_has_private and try_to_release_page are used to filter writeback
pages.  This does not work for xfs with blocksize equal to or larger
than pagesize, because in such case xfs has no page->private.

This makes collapse_file bail out early for writeback page.  Otherwise,

CVE-2021-41229 (Low severity, published 2021-11-11)
CVSS score: 4.3 (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CWE: CWE-401
Description: BlueZ is a Bluetooth protocol stack for Linux. In affected versions a vulnerability exists in sdp_cstate_alloc_buf which allocates memory which will always be hung in the singly linked list of cstates and will not be freed. This will cause a memory leak over time. The data can be a very large object, which can be caused by an attacker continuously sending sdp packets and this may cause the service of the target device to crash.
