chromium-browser: Insufficient policy enforcement in networking

common/session.c in Claws Mail before 3.17.6 has a protocol violation because suffix data after STARTTLS is mishandled.

In HylaFAX+ through 7.0.2 and HylaFAX Enterprise, the faxsetup utility calls chown on files in user-owned directories. By winning a race, a local attacker could use this to escalate his privileges to root.

Path traversal and files overwrite with unsquashfs

Singularity (an open source container platform) from version 3.1.1 through 3.6.3 has a vulnerability. Due to insecure handling of path traversal and the lack of path sanitization within `unsquashfs`, it is possible to overwrite/create any files on the host filesystem during the extraction with a crafted squashfs filesystem. The extraction occurs automatically for unprivileged (either installation or with `allow setuid = no`) run of Singularity when a user attempt to run an image which is a local SIF image or a single file containing a squashfs filesystem and is coming from remote sources `library://` or `shub://`. Image build is also impacted in a more serious way as it can be used by a root user, allowing an attacker to overwrite/create files leading to a system compromise, so far bootstrap methods `library`, `shub` and `localimage` are triggering the squashfs extraction. This issue is addressed in Singularity 3.6.4. All users are advised to upgrade to 3.6.4 especially if they use Singularity mainly for building image as root user. There is no solid workaround except to temporary avoid to use unprivileged mode with single file images in favor of sandbox images instead. Regarding image build, temporary avoid to build from `library` and `shub` sources and as much as possible use `--fakeroot` or a VM for that.

librepo: missing path validation in repomd.xml may lead to directory traversal

A flaw was found in librepo in versions before 1.12.1. A directory traversal vulnerability was found where it failed to sanitize paths in remote repository metadata. An attacker controlling a remote repository may be able to copy files outside of the destination directory on the targeted system via path traversal. This flaw could potentially result in system compromise via the overwriting of critical system files. The highest threat from this flaw is to users that make use of untrusted third-party repositories.

An issue was discovered in Icinga2 before v2.12.0-rc1. The prepare-dirs script (run as part of the icinga2 systemd service) executes chmod 2750 /run/icinga2/cmd. /run/icinga2 is under control of an unprivileged user by default. If /run/icinga2/cmd is a symlink, then it will by followed and arbitrary files can be changed to mode 2750 by the unprivileged icinga2 user.

An issue was discovered in LinuxTV xawtv before 3.107. The function dev_open() in v4l-conf.c does not perform sufficient checks to prevent an unprivileged caller of the program from opening unintended filesystem paths. This allows a local attacker with access to the v4l-conf setuid-root program to test for the existence of arbitrary files and to trigger an open on arbitrary files with mode O_RDWR. To achieve this, relative path components need to be added to the device path, as demonstrated by a v4l-conf -c /dev/../root/.bash_history command.

An issue was discovered in ssl.c in Axel before 2.17.8. The TLS implementation lacks hostname verification.

grafana: SSRF incorrect access control vulnerability allows unauthenticated users to make grafana send HTTP requests to any URL

The avatar feature in Grafana 3.0.1 through 7.0.1 has an SSRF Incorrect Access Control issue. This vulnerability allows any unauthenticated user/client to make Grafana send HTTP requests to any URL and return its result to the user/client. This can be used to gain information about the network that Grafana is running on. Furthermore, passing invalid URL objects could be used for DOS'ing Grafana via SegFault.

GraphicsMagick through 1.3.35 has a heap-based buffer overflow in ReadMNGImage in coders/png.c.

Roundcube Webmail before 1.4.4 allows attackers to include local files and execute code via directory traversal in a plugin name to rcube_plugin_api.php.

An issue was discovered in Roundcube Webmail before 1.4.4. There is a cross-site scripting (XSS) vulnerability in rcube_washtml.php because JavaScript code can occur in the CDATA of an HTML message.

An issue has been found in PowerDNS Recursor 4.1.0 through 4.3.0 where records in the answer section of a NXDOMAIN response lacking an SOA were not properly validated in SyncRes::processAnswer, allowing an attacker to bypass DNSSEC validation.
