FreeRADIUS before 3.0.19 does not prevent use of reflection for authentication spoofing, aka a "Dragonblood" issue, a similar issue to CVE-2019-9497.

FreeRADIUS before 3.0.19 mishandles the "each participant verifies that the received scalar is within a range, and that the received group element is a valid point on the curve being used" protection mechanism, aka a "Dragonblood" issue, a similar issue to CVE-2019-9498 and CVE-2019-9499.

vpn-user-portal (aka eduVPN or Let's Connect!) before 2.3.14, as packaged for Debian 10, Debian 11, and Fedora, allows remote authenticated users to obtain OS filesystem access, because of the interaction of QR codes with an exec that uses the -r option. This can be leveraged to obtain additional VPN access.

A vulnerability was found in libvirt >= 4.1.0 in the virtlockd-admin.socket and virtlogd-admin.socket systemd units. A missing SocketMode configuration parameter allows any user on the host to connect using virtlockd-admin-sock or virtlogd-admin-sock and perform administrative tasks against the virtlockd and virtlogd daemons.

A stack-based buffer overflow within GNOME gcab through 0.7.4 can be exploited by malicious attackers to cause a crash or, potentially, execute arbitrary code via a crafted .cab file.

udisks before 1.0.3 allows a local user to load arbitrary Linux kernel modules.

A vulnerability was found in gnutls versions from 3.5.8 before 3.6.7. A memory corruption (double free) vulnerability in the certificate verification API. Any client or server application that verifies X.509 certificates with GnuTLS 3.5.8 or later is affected.

It was found that cockpit before version 184 used glib's base64 decode functionality incorrectly resulting in a denial of service attack. An unauthenticated attacker could send a specially crafted request with an invalid base64-encoded cookie which could cause the web service to crash.

In Pulp before version 2.16.2, secrets are passed into override_config when triggering a task and then become readable to all users with read access on the distributor/importer. An attacker with API access can then view these secrets.

Multiple integer overflows in (1) OPVPOutputDev.cxx and (2) oprs/OPVPSplash.cxx in the pdftoopvp filter in CUPS and cups-filters before 1.0.47 allow remote attackers to execute arbitrary code via a crafted PDF file, which triggers a heap-based buffer overflow.

Heap-based buffer overflow in the pdftoopvp filter in CUPS and cups-filters before 1.0.47 allows remote attackers to execute arbitrary code via a crafted PDF file.

Libtiff: integer overflow in tiffcp.c

Libtiff: potential integer overflow in raw2tiff.c

Imagemagick: heap-buffer-overflow in coders/tiff.c

A flaw was found in cri-o, as a result of all pod-related processes being placed in the same memory cgroup. This can result in container management (conmon) processes being killed if a workload process triggers an out-of-memory (OOM) condition for the cgroup. An attacker could abuse this flaw to get host network access on an cri-o host.

jose vulnerable to resource exhaustion via specifically crafted JWE with compressed plaintext

A flaw was found in the default configuration of dnsmasq, as shipped with Fedora versions prior to 31 and in all versions Red Hat Enterprise Linux, where it listens on any interface and accepts queries from addresses outside of its local subnet. In particular, the option `local-service` is not enabled. Running dnsmasq in this manner may inadvertently make it an open resolver accessible from any address on the internet. This flaw allows an attacker to conduct a Distributed Denial of Service (DDoS) against other systems.

A flaw was found in the Linux kernel's vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS). Versions 3.10, 4.14 and 4.18 are vulnerable.

Kernel: xfrm: null pointer dereference in xfrm_update_ae_params()

Libtiff: memory leak in tiffcrop.c

Kernel: smsusb: use-after-free caused by do_submit_urb()

A flaw was found in the permissions of a log file created by kexec-tools. This flaw allows a local unprivileged user to read this file and leak kernel internal information from a previous panic. The highest threat from this vulnerability is to confidentiality. This flaw affects kexec-tools shipped by Fedora versions prior to 2.0.21-8 and RHEL versions prior to 2.0.20-47.

Kernel: xfrm: out-of-bounds read of xfrma_mtimer_thresh nlattr

Kernel: cxgb4: use-after-free in ch_flower_stats_cb()

setup before version 2.11.4-1.fc28 in Fedora and Red Hat Enterprise Linux added /sbin/nologin and /usr/sbin/nologin to /etc/shells. This violates security assumptions made by pam_shells and some daemons which allow access based on a user's shell being listed in /etc/shells. Under some circumstances, users which had their shell changed to /sbin/nologin could still access the system.

A vulnerability was found in sssd. If a user was configured with no home directory set, sssd would return '/' (the root directory) instead of '' (the empty string / no home directory). This could impact services that restrict the user's filesystem access to within their home directory through chroot() etc. All versions before 2.1 are vulnerable.

denyhosts 2.6 uses an incorrect regular expression when analyzing authentication logs, which allows remote attackers to cause a denial of service (incorrect block of IP addresses) via crafted login names.

The parse function in Email::Address module before 1.905 for Perl uses an inefficient regular expression, which allows remote attackers to cause a denial of service (CPU consumption) via an empty quoted string in an RFC 2822 address.

puppetmasterd in puppet 0.24.6 does not reset supplementary groups when it switches to a different user, which might allow local users to access restricted files.

GMXRC.bash in Gromacs 4.5.1 and earlier places a zero-length directory name in the LD_LIBRARY_PATH, which allows local users to gain privileges via a Trojan horse shared library in the current working directory. NOTE: CVE disputes this issue because the GMXLDLIB value is always added to the beginning of LD_LIBRARY_PATH at a later point in the script

rssh 2.3.2, as used by Debian, Fedora, and others, when the rsync protocol is enabled, allows local users to bypass intended restricted shell access via a (1) "-e" or (2) "--" command line option.

The OPVPWrapper::loadDriver function in oprs/OPVPWrapper.cxx in the pdftoopvp filter in CUPS and cups-filters before 1.0.47 allows local users to gain privileges via a Trojan horse driver in the same directory as the PDF file.

The dtls1_get_message_fragment function in d1_both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote attackers to cause a denial of service (recursion and client crash) via a DTLS hello message in an invalid DTLS handshake.

The ssl3_send_client_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h, when an anonymous ECDH cipher suite is used, allows remote attackers to cause a denial of service (NULL pointer dereference and client crash) by triggering a NULL certificate value.

Go JOSE vulnerable to Improper Handling of Highly Compressed Data (Data Amplification)

A vulnerability was found in moodle before versions 3.6.3 and 3.5.5. There was a link to site home within the the Boost theme's secure layout, meaning students could navigate out of the page.

yum-rhn-plugin in Red Hat Network Client Tools (aka rhn-client-tools) on Red Hat Enterprise Linux (RHEL) 5 and Fedora uses world-readable permissions for the /var/spool/up2date/loginAuth.pkl file, which allows local users to access the Red Hat Network profile, and possibly prevent future security updates, by leveraging authentication data from this file.
