CVE-2019-3837 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2022-12-02 4.9 MEDIUM 6.1 MEDIUM
It was found that the net_dma code in tcp_recvmsg() in the 2.6.32 kernel as shipped in RHEL6 is thread-unsafe. So an unprivileged multi-threaded userspace application calling recvmsg() for the same network socket in parallel executed on ioatdma-enabled hardware with net_dma enabled can leak the memory, crash the host leading to a denial-of-service or cause a random memory corruption.
CVE-2022-3821 3 Fedoraproject, Redhat, Systemd Project 3 Fedora, Enterprise Linux, Systemd 2022-12-02 N/A 5.5 MEDIUM
An off-by-one Error issue was discovered in Systemd in format_timespan() function of time-util.c. An attacker could supply specific values for time and accuracy that leads to buffer overrun in format_timespan(), leading to a Denial of Service.
CVE-2022-2625 3 Fedoraproject, Postgresql, Redhat 3 Fedora, Postgresql, Enterprise Linux 2022-12-02 N/A 8.0 HIGH
A vulnerability was found in PostgreSQL. This attack requires permission to create non-temporary objects in at least one schema, the ability to lure or wait for an administrator to create or update an affected extension in that schema, and the ability to lure or wait for a victim to use the object targeted in CREATE OR REPLACE or CREATE IF NOT EXISTS. Given all three prerequisites, this flaw allows an attacker to run arbitrary code as the victim role, which may be a superuser.
CVE-2020-35501 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2022-12-02 3.6 LOW 3.4 LOW
A flaw was found in the Linux kernels implementation of audit rules, where a syscall can unexpectedly not be correctly not be logged by the audit subsystem
CVE-2021-26252 3 Fedoraproject, Htmldoc Project, Redhat 3 Fedora, Htmldoc, Enterprise Linux 2022-12-02 6.8 MEDIUM 7.8 HIGH
A flaw was found in htmldoc in v1.9.12. Heap buffer overflow in pspdf_prepare_page(),in ps-pdf.cxx may lead to execute arbitrary code and denial of service.
CVE-2019-14379 7 Apple, Debian, Fasterxml and 4 more 25 Xcode, Debian Linux, Jackson-databind and 22 more 2022-12-02 7.5 HIGH 9.8 CRITICAL
SubTypeValidator.java in FasterXML jackson-databind before 2.9.9.2 mishandles default typing when ehcache is used (because of net.sf.ehcache.transaction.manager.DefaultTransactionManagerLookup), leading to remote code execution.
CVE-2022-0485 1 Redhat 2 Enterprise Linux, Libnbd 2022-12-01 N/A 4.8 MEDIUM
A flaw was found in the copying tool `nbdcopy` of libnbd. When performing multi-threaded copies using asynchronous nbd calls, nbdcopy was blindly treating the completion of an asynchronous command as successful, rather than checking the *error parameter. This could result in the silent creation of a corrupted destination image.
CVE-2021-3827 1 Redhat 4 Enterprise Linux, Keycloak, Openshift Container Platform and 1 more 2022-11-30 N/A 6.8 MEDIUM
A flaw was found in keycloak, where the default ECP binding flow allows other authentication flows to be bypassed. By exploiting this behavior, an attacker can bypass the MFA authentication by sending a SOAP request with an AuthnRequest and Authorization header with the user's credentials. The highest threat from this vulnerability is to confidentiality and integrity.
CVE-2021-35938 3 Fedoraproject, Redhat, Rpm 3 Fedora, Enterprise Linux, Rpm 2022-11-29 N/A 6.7 MEDIUM
A symbolic link issue was found in rpm. It occurs when rpm sets the desired permissions and credentials after installing a file. A local unprivileged user could use this flaw to exchange the original file with a symbolic link to a security-critical file and escalate their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2021-3623 3 Fedoraproject, Libtpms Project, Redhat 3 Fedora, Libtpms, Enterprise Linux 2022-11-29 3.6 LOW 6.1 MEDIUM
A flaw was found in libtpms. The flaw can be triggered by specially-crafted TPM 2 command packets containing illegal values and may lead to an out-of-bounds access when the volatile state of the TPM 2 is marshalled/written or unmarshalled/read. The highest threat from this vulnerability is to system availability.
CVE-2020-1712 3 Debian, Redhat, Systemd Project 7 Debian Linux, Ceph Storage, Discovery and 4 more 2022-11-29 4.6 MEDIUM 7.8 HIGH
A heap use-after-free vulnerability was found in systemd before version v245-rc1, where asynchronous Polkit queries are performed while handling dbus messages. A local unprivileged attacker can abuse this flaw to crash systemd services or potentially execute code and elevate their privileges, by sending specially crafted dbus messages.
CVE-2021-4207 3 Debian, Qemu, Redhat 3 Debian Linux, Qemu, Enterprise Linux 2022-11-29 4.6 MEDIUM 8.2 HIGH
A flaw was found in the QXL display device emulation in QEMU. A double fetch of guest controlled values `cursor->header.width` and `cursor->header.height` can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. A malicious privileged guest user could use this flaw to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process.
CVE-2021-4217 3 Fedoraproject, Redhat, Unzip Project 3 Fedora, Enterprise Linux, Unzip 2022-11-29 N/A 3.3 LOW
A flaw was found in unzip. The vulnerability occurs due to improper handling of Unicode strings, which can lead to a null pointer dereference. This flaw allows an attacker to input a specially crafted zip file, leading to a crash or code execution.
CVE-2022-27650 3 Crun Project, Fedoraproject, Redhat 4 Crun, Fedora, Enterprise Linux and 1 more 2022-11-28 6.0 MEDIUM 7.5 HIGH
A flaw was found in crun where containers were incorrectly started with non-empty default permissions. A vulnerability was found in Moby (Docker Engine) where containers were started incorrectly with non-empty inheritable Linux process capabilities. This flaw allows an attacker with access to programs with inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs.
CVE-2021-3632 1 Redhat 3 Enterprise Linux, Keycloak, Single Sign-on 2022-11-23 N/A 7.5 HIGH
A flaw was found in Keycloak. This vulnerability allows anyone to register a new security device or key when there is not a device already registered for any user by using the WebAuthn password-less login flow.
CVE-2022-2153 4 Debian, Fedoraproject, Linux and 1 more 4 Debian Linux, Fedora, Linux Kernel and 1 more 2022-11-21 N/A 5.5 MEDIUM
A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service.
CVE-2022-2905 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2022-11-21 N/A 5.5 MEDIUM
An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to gain unauthorized access to data.
CVE-2020-25641 5 Canonical, Debian, Linux and 2 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2022-11-21 4.9 MEDIUM 5.5 MEDIUM
A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block device, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-14355 5 Canonical, Debian, Opensuse and 2 more 10 Ubuntu Linux, Debian Linux, Leap and 7 more 2022-11-21 6.5 MEDIUM 6.6 MEDIUM
Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system, before spice-0.14.2-1. Both the SPICE client (spice-gtk) and server are affected by these flaws. These flaws allow a malicious client or server to send specially crafted messages that, when processed by the QUIC image compression algorithm, result in a process crash or potential code execution.
CVE-2017-3085 6 Adobe, Apple, Google and 3 more 11 Flash Player, Flash Player Desktop Runtime, Mac Os X and 8 more 2022-11-16 4.3 MEDIUM 7.4 HIGH
Adobe Flash Player versions 26.0.0.137 and earlier have a security bypass vulnerability that leads to information disclosure when performing URL redirect.
