Use-after-free vulnerability in hw/ide/ahci.c in QEMU, when built with IDE AHCI Emulation support, allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via an invalid AHCI Native Command Queuing (NCQ) AIO command.
CVE-2022-0207 2 Ovirt, Redhat 5 Vdsm, Enterprise Linux, Virtualization and 2 more 2023-02-12 N/A 4.7 MEDIUM
A race condition was found in vdsm. Functionality to obfuscate sensitive values in log files that may lead to values being stored in clear text.
CVE-2014-0160 11 Canonical, Debian, Fedoraproject and 8 more 33 Ubuntu Linux, Debian Linux, Fedora and 30 more 2023-02-10 5.0 MEDIUM 7.5 HIGH
The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug.
CVE-2022-27666 5 Debian, Fedoraproject, Linux and 2 more 21 Debian Linux, Fedora, Linux Kernel and 18 more 2023-02-01 4.6 MEDIUM 7.8 HIGH
A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat.
CVE-2021-3677 3 Fedoraproject, Postgresql, Redhat 7 Fedora, Postgresql, Enterprise Linux and 4 more 2023-01-31 4.0 MEDIUM 6.5 MEDIUM
A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. However, undiscovered variants of the attack may be independent of that setting.
CVE-2021-4154 3 Linux, Netapp, Redhat 4 Linux Kernel, Hci Baseboard Management Controller, Enterprise Linux and 1 more 2023-01-19 7.2 HIGH 8.8 HIGH
A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting the fsconfig syscall parameter leading to a container breakout and a denial of service on the system.
CVE-2022-0330 4 Fedoraproject, Linux, Netapp and 1 more 46 Fedora, Linux Kernel, H300e and 43 more 2022-12-07 4.6 MEDIUM 7.8 HIGH
A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or escalate their privileges on the system.
CVE-2019-3804 3 Cockpit-project, Fedoraproject, Redhat 3 Cockpit, Fedora, Virtualization 2022-11-07 5.0 MEDIUM 7.5 HIGH
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.
CVE-2022-2805 1 Redhat 1 Virtualization 2022-11-07 N/A 6.5 MEDIUM
A flaw was found in ovirt-engine, which leads to the logging of plaintext passwords in the log file when using otapi-style. This flaw allows an attacker with sufficient privileges to read the log file, leading to confidentiality loss.
CVE-2022-2078 3 Debian, Linux, Redhat 4 Debian Linux, Linux Kernel, Enterprise Linux and 1 more 2022-10-26 2.1 LOW 5.5 MEDIUM
A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and possibly to run code.
CVE-2021-3621 3 Fedoraproject, Redhat, Sssd 8 Fedora, Enterprise Linux, Enterprise Linux Eus and 5 more 2022-10-24 9.3 HIGH 8.8 HIGH
A flaw was found in SSSD, where the sssctl command was vulnerable to shell command injection via the logs-fetch and cache-expire subcommands. This flaw allows an attacker to trick the root user into running a specially crafted sssctl command, such as via sudo, to gain root access. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2021-3634 6 Debian, Fedoraproject, Libssh and 3 more 7 Debian Linux, Fedora, Libssh and 4 more 2022-10-07 4.0 MEDIUM 6.5 MEDIUM
A flaw has been found in libssh in versions prior to 0.9.6. The SSH protocol keeps track of two shared secrets during the lifetime of the session. One of them is called secret_hash and the other session_id. Initially, both of them are the same, but after key re-exchange, previous session_id is kept and used as an input to new secret_hash. Historically, both of these buffers had shared length variable, which worked as long as these buffers were same. But the key re-exchange operation can also change the key exchange method, which can be based on hash of different size, eventually creating "secret_hash" of different size than the session_id has. This becomes an issue when the session_id memory is zeroed or when it is used again during second key re-exchange.
CVE-2020-27827 5 Fedoraproject, Lldpd Project, Openvswitch and 2 more 27 Fedora, Lldpd, Openvswitch and 24 more 2022-10-06 7.1 HIGH 7.5 HIGH
A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2018-16881 3 Debian, Redhat, Rsyslog 13 Debian Linux, Enterprise Linux, Enterprise Linux Desktop and 10 more 2022-10-06 5.0 MEDIUM 7.5 HIGH
A denial of service vulnerability was found in rsyslog in the imptcp module. An attacker could send a specially crafted message to the imptcp socket, which would cause rsyslog to crash. Versions before 8.27.0 are vulnerable.
CVE-2022-2132 4 Debian, Dpdk, Fedoraproject and 1 more 8 Debian Linux, Data Plane Development Kit, Fedora and 5 more 2022-09-06 N/A 8.6 HIGH
A permissive list of allowed inputs flaw was found in DPDK. This issue allows a remote attacker to cause a denial of service triggered by sending a crafted Vhost header to DPDK.
CVE-2019-1559 13 Canonical, Debian, F5 and 10 more 90 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 87 more 2022-08-19 4.3 MEDIUM 5.9 MEDIUM
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). Fixed in OpenSSL 1.0.2r (Affected 1.0.2-1.0.2q).
