Missing handle permissions check in SMB1/2/3 ChangeNotify
CVE: CVE-2020-14318
Component: samba
CWE: CWE-266
Severity: Moderate
CVSS v3: 4.5/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
Release date: 2020-10-29T00:00:00+00:00

A flaw was found in the way Samba handled file and directory permissions. This flaw allows an authenticated user to gain access to certain file and directory information, which otherwise would be unavailable. The highest threat from this vulnerability is to confidentiality.

As Samba internally opens an underlying file system handle on a directory when a client requests an open, even for FILE_READ_ATTRIBUTES then if the underlying file system permissions don't allow "r" (read) access for the connected user, then the handle open request will be denied.

"r" access is the normal permission needed to list or otherwise reveal the contents of a directory, so if a connected user has "r" access then they will be able to list the directory contents normally, and the information received by a ChangeNofity request is already available to the user.

The security issue occurs if the Administrator or directory owner had set more restrictive Windows ACL permissions on the directory to disallow read access to the user, and this permissions change was not reflected in the underlying file system permissions.

This will only occur if Samba is configured with VFS modules to decouple the underlying file system permissions from the Windows ACLs, by setting up a share with the settings:

[vulnerable_share]
        vfs_objects = vfs_acl_xattr
        acl_xattr:ignore system acls = yes
Denial of Service due to stack overflow in doproxyconnect() function
CVE: CVE-2020-37182
Component: redir
CVSS v3: 7.5/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Release date: 2020-01-01T00:00:00+00:00

A flaw was found in redir. A remote attacker can exploit a stack overflow vulnerability in the `doproxyconnect()` function by sending oversized input. This vulnerability, caused by improper length checking in the `sprintf()` function, allows attackers to overwrite memory, leading to a segmentation fault and program termination. This results in a Denial of Service (DoS) for the application.

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.

CVE: CVE-2020-4033
Component: freerdp
CWE: CWE-125
Severity: Low
CVSS v3: 6.4/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L
Release date: 2020-06-22T00:00:00+00:00

In FreeRDP before version 2.1.2, there is an out of bounds read in RLEDECOMPRESS. All FreeRDP based clients with sessions with color depth < 32 are affected. This is fixed in version 2.1.2.

Download origin spoofing via redirect
CVE: CVE-2020-15677
Component: Mozilla
CWE: CWE-601
Severity: Moderate
CVSS v3: 6.0/CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Release date: 2020-09-22T00:00:00+00:00

The Mozilla Foundation Security Advisory describes this flaw as:

By exploiting an Open Redirect vulnerability on a website, an attacker could have spoofed the site displayed in the download file dialog to show the original site (the one suffering from the open redirect) rather than the site the file was actually downloaded from.

Release date: 2020-01-01T00:00:00+00:00

A flaw was found in darkhttpd. Invalid error handling allows remote attackers to cause denial-of-service by accessing a file with a large modification date. The highest threat from this vulnerability is to system availability.

certificate exceptions stored as authorities
CVE: CVE-2020-26117
Component: tigervnc
CWE: CWE-296
Severity: Moderate
CVSS v3: 8.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N
Release date: 2020-09-18T00:00:00+00:00

In rfb/CSecurityTLS.cxx and rfb/CSecurityTLS.java in TigerVNC before 1.11.0, viewers mishandle TLS certificate exceptions. They store the certificates as authorities, meaning that the owner of a certificate could impersonate any server after a client had added an exception.


Remediation:
This flaw can be mitigated by not making certificate exceptions in the affected versions of tigervnc, and therefore they will not be stored as authorities.
Insufficient access control vulnerability in PowerCap Framework
CVE: CVE-2020-8694
Component: kernel
CWE: CWE-200
Severity: Moderate
CVSS v3: 5.6/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Release date: 2020-11-10T00:00:00+00:00

A flaw was found in the Linux kernel's implementation of Intel's Running Average Power Limit (RAPL) implementation. A local attacker could infer secrets by measuring power usage and also infer private data by observing the power usage of calculations performed on the data.


Remediation:
A temporary measure would be to remove the ability for non-root users 
to read the current RAPL energy reporting metrics.

This can be done with the command:

$ sudo chmod 400 /sys/class/powercap/intel_rapl/*/energy_uj

This mitigation will only work on the current boot and will need to be reapplied at each system boot to remain in effect.

Don't use Browser's LocalStorage for storing JWT but Secure Cookies with proper HTTP Headers
CVE: CVE-2020-27839
Component: ceph-dashboard
CWE: CWE-522
Severity: Moderate
CVSS v3: 5.2/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N
Release date: 2020-03-13T00:00:00+00:00

A flaw was found in ceph-dashboard. The JSON Web Token (JWT) used for user authentication is stored by the frontend application in the browser’s localStorage which is potentially vulnerable to attackers via XSS attacks. The highest threat from this vulnerability is to data confidentiality and integrity.

Statement: * Red Hat Ceph Storage 3 is not affected as it does not use authentication for the dashboard.

* Red Hat OpenStack Platform deployments use the ceph package directly from the Ceph channel; the RHOSP package will not be updated at this time.

* Red Hat OpenShift Container Storage (RHOCS) 4 shipped ceph package for the usage of RHOCS 4.2 only which has reached End of Life. The shipped version of ceph package is neither used nor supported with the release of RHOCS 4.3.

* Red Hat Enterprise Linux 8 does not include the ceph dashboard component.

Remediation:
Do not store sensitive data in HTML5 localStorage, not even temporarily. Use cookies with appropriate security flags (secure, HttpOnly, SameSite).
Crafted URL containing new lines, empty host or lacks a scheme can cause credential leak
CVE: CVE-2020-11008
Component: git
CWE: CWE-20
Severity: Important
CVSS v3: 7.5/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Release date: 2020-04-20T18:00:00+00:00

A flaw was found in git where credentials can be leaked through the use of a crafted URL. The crafted URL must contain a newline, empty host, or lack a scheme so that the credential helper is fulled into giving the information of a different host to the client. The highest threat from this vulnerability is to data confidentiality.

Statement: Red Hat Enterprise Linux 6 is not affected by this flaw as the vulnerable version of git, version 1.7.9-rc0 and later, was never made available for this product.

Remediation:
The most complete workaround is to disable credential helpers altogether:

~~~
git config --unset credential.helper
git config --global --unset credential.helper
git config --system --unset credential.helper
~~~

An alternative is to avoid malicious URLs:

1. Examine the hostname and username portion of URLs fed to git clone or git fetch for the presence of encoded newlines (%0A) or syntactic oddities (e.g., http:///host with three slashes).
2. Avoid using submodules with untrusted repositories (don't use git clone --recurse-submodules; use git submodule update only after examining the URLs found in .gitmodules).
3. Avoid tools which may run git clone on untrusted URLs under the hood.
4. Avoid using the credential helper by only cloning publicly available repositories.
Inappropriate implementation in Omnibox

out-of-bounds-write from strncpy() may lead to arbitrary code execution

Component: gnuplot
CWE: CWE-125
Severity: Moderate

Release date: 2020-09-16T00:00:00+00:00

A flaw was found in gnuplot. An execution path from com_line() in command.c results in strncpy() being called with an incorrect length, causing an out-of-bounds write. A local attacker could exploit this flaw by passing a specially crafted input file to gnuplot. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Statement: gnuplot as shipped with Red Hat Enterprise Linux 5, 6, 7, and 8 is not affected because the vulnerable code was introduced in a subsequent version of gnuplot.
