tracing: Fix sleeping function called from invalid context on RT kernel
CVE: CVE-2022-49322
Component: kernel
CWE: CWE-667
Severity: Low
CVSS v3: 5.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H
Release date: 2022-01-01T00:00:00+00:00

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

tracing: Fix sleeping function called from invalid context on RT kernel

When setting bootparams="trace_event=initcall:initcall_start tp_printk=1" in the
cmdline, the output_printk() was called, and the spin_lock_irqsave() was called in the
atomic and irq disable interrupt context suitation. On the PREEMPT_RT kernel,
these locks are replaced with sleepable rt-spinlock, so the stack calltrace will
be triggered.
Fix it by raw_spin_lock_irqsave when PREEMPT_RT and "trace_event=initcall:initcall_start
tp_printk=1" enabled.

certificate verification is skipped for connections to OIDC providers
CVE: CVE-2022-31105
Component: argo-cd
CWE: CWE-599
Severity: Important
CVSS v3: 8.3/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H
Release date: 2022-07-13T00:00:00+00:00

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Argo CD starting with version 0.4.0 and prior to 2.2.11, 2.3.6, and 2.4.5 is vulnerable to an improper certificate validation bug which could cause Argo CD to trust a malicious (or otherwise untrustworthy) OpenID Connect (OIDC) provider. A patch for this vulnerability has been released in Argo CD versions 2.4.5, 2.3.6, and 2.2.11. There are no complete workarounds, but a partial workaround is available. Those who use an external OIDC provider (not the bundled Dex instance), can mitigate the issue by setting the `oidc.config.rootCA` field in the `argocd-cm` ConfigMap. This mitigation only forces certificate validation when the API server handles login flows. It does not force certificate verification when verifying tokens on API calls.

Statement: This issue is already fixed in current Red Hat GitOps releases (1.4.11, 1.5.5, 1.6.0)

secret leakage into server logs
CVE: CVE-2022-24757
Component: <dev-python/jupyter_server-1.15.6
Release date: 2022-03-23T00:00:00+00:00

The Jupyter Server provides the backend (i.e. the core services, APIs, and REST endpoints) for Jupyter web applications. Prior to version 1.15.4, unauthorized actors can access sensitive information from server logs. Anytime a 5xx error is triggered, the auth cookie and other header values are recorded in Jupyter Server logs by default. Considering these logs do not require root access, an attacker can monitor these logs, steal sensitive auth/cookie information, and gain access to the Jupyter server. Jupyter Server version 1.15.4 contains a patch for this issue. There are currently no known workarounds.

Statement: Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery.

btrfs: fix race between quota enable and quota rescan ioctl
CVE: CVE-2022-50379
Component: kernel
Severity: Low
CVSS v3: 5.6/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Release date: 2022-01-01T00:00:00+00:00

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

btrfs: fix race between quota enable and quota rescan ioctl

When enabling quotas, at btrfs_quota_enable(), after committing the
transaction, we change fs_info->quota_root to point to the quota root we
created and set BTRFS_FS_QUOTA_ENABLED at fs_info->flags. Then we try
to start the qgroup rescan worker, first by initializing it with a call
to qgroup_rescan_init() - however if that fails we end up freeing the
quota root but we leave fs_info->quota_root still pointing to it, this
can later result in a use-after-free somewhere else.

We have previously set the flags BTRFS_FS_QUOTA_ENABLED and
BTRFS_QGROUP_STATUS_FLAG_ON, so we can only fail with -EINPROGRESS at
btrfs_quota_enable(), which is possible if someone already called the
quota rescan ioctl, and therefore started the rescan worker.

So fix this by ignoring an -EINPROGRESS and asserting we can't get any
other error.

buffer over-read in utf_ptr2char() in mbyte.c
CVE: CVE-2022-1927
Component: vim
CWE: CWE-125
Severity: Moderate
CVSS v3: 7.7/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Release date: 2022-05-22T00:00:00+00:00

A flaw was found in vim. The vulnerability occurs due to Illegal memory access and leads to a buffer over-read vulnerability in the utf_ptr2char function. This flaw allows an attacker to input a specially crafted file, leading to a crash or code execution.


Remediation:
Untrusted vim scripts with -s [scriptin] are not recommended to run.
Lookups involving a DNAME could trigger an assertion failure when 'synth-from-dnssec' was enabled (which is the default)
CVE: CVE-2022-0635
Component: bind
CWE: CWE-617
Severity: Important
CVSS v3: 7.5/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Release date: 2022-03-16T00:00:00+00:00

An assertion check flaw was found in BIND, with a refactoration of RFC 8198 Aggressive Use of the DNSSEC-Validated Cache feature (synth-from-dnssec). The repeated patterns of specific queries to servers with this feature enabled could cause an INSIST failure in query.c:query_dname, which results in unexpected termination. This flaw allows a remote attacker to use a series of specific queries to trigger a failed assertion check that causes the named process to terminate, leading to a denial of service.

Statement: The vulnerability affects BIND resolvers running 9.18.0 with both dnssec-validation and synth-from-dnssec enabled. (Note that dnssec-validation auto; is the default setting unless configured otherwise in named.conf and that enabling dnssec-validation automatically enables synth-from-dnssec unless explicitly disabled) 

This flaw only affects BIND-9.18.0, whereas Red Hat ships BIND-9.16 and lower versions. Therefore, versions of BIND shipped with Red Hat Products are not affected by this flaw.
