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-2020-25717 5 Canonical, Debian, Fedoraproject and 2 more 25 Ubuntu Linux, Debian Linux, Fedora and 22 more 2024-02-28 8.5 HIGH 8.1 HIGH
A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation.
CVE-2021-4154 3 Linux, Netapp, Redhat 4 Linux Kernel, Hci Baseboard Management Controller, Enterprise Linux and 1 more 2024-02-28 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-2021-3501 4 Fedoraproject, Linux, Netapp and 1 more 27 Fedora, Linux Kernel, Cloud Backup and 24 more 2024-02-28 3.6 LOW 7.1 HIGH
A flaw was found in the Linux kernel in versions before 5.12. The value of internal.ndata, in the KVM API, is mapped to an array index, which can be updated by a user process at anytime which could lead to an out-of-bounds write. The highest threat from this vulnerability is to data integrity and system availability.
CVE-2021-3634 6 Debian, Fedoraproject, Libssh and 3 more 7 Debian Linux, Fedora, Libssh and 4 more 2024-02-28 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-2019-14850 2 Nbdkit Project, Redhat 4 Nbdkit, Enterprise Linux, Enterprise Linux Server and 1 more 2024-02-28 2.6 LOW 3.7 LOW
A denial of service vulnerability was discovered in nbdkit 1.12.7, 1.14.1 and 1.15.1. An attacker could connect to the nbdkit service and cause it to perform a large amount of work in initializing backend plugins, by simply opening a connection to the service. This vulnerability could cause resource consumption and degradation of service in nbdkit, depending on the plugins configured on the server-side.
CVE-2020-27827 5 Fedoraproject, Lldpd Project, Openvswitch and 2 more 27 Fedora, Lldpd, Openvswitch and 24 more 2024-02-28 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-2020-35497 2 Ovirt, Redhat 2 Ovirt-engine, Virtualization 2024-02-28 4.0 MEDIUM 6.5 MEDIUM

CVE-2019-14287 7 Canonical, Debian, Fedoraproject and 4 more 15 Ubuntu Linux, Debian Linux, Fedora and 12 more 2024-02-28 9.0 HIGH 8.8 HIGH
In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID. For example, this allows bypass of !root configuration, and USER= logging, for a "sudo -u \#$((0xffffffff))" command.
CVE-2019-14816 7 Canonical, Debian, Fedoraproject and 4 more 54 Ubuntu Linux, Debian Linux, Fedora and 51 more 2024-02-28 7.2 HIGH 7.8 HIGH
There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code.
CVE-2019-14859 2 Python-ecdsa Project, Redhat 4 Python-ecdsa, Ceph Storage, Openstack and 1 more 2024-02-28 6.4 MEDIUM 9.1 CRITICAL
A flaw was found in all python-ecdsa versions before 0.13.3, where it did not correctly verify whether signatures used DER encoding. Without this verification, a malformed signature could be accepted, making the signature malleable. Without proper verification, an attacker could use a malleable signature to create false transactions.
CVE-2015-1780 1 Redhat 2 Ovirt-engine, Virtualization 2024-02-28 4.0 MEDIUM 6.5 MEDIUM
oVirt users with MANIPULATE_STORAGE_DOMAIN permissions can attach a storage domain to any data-center
CVE-2019-10161 2 Canonical, Redhat 5 Ubuntu Linux, Enterprise Linux, Libvirt and 2 more 2024-02-28 7.2 HIGH 7.8 HIGH
It was discovered that libvirtd before versions 4.10.1 and 5.4.1 would permit read-only clients to use the virDomainSaveImageGetXMLDesc() API, specifying an arbitrary path which would be accessed with the permissions of the libvirtd process. An attacker with access to the libvirtd socket could use this to probe the existence of arbitrary files, cause denial of service or cause libvirtd to execute arbitrary programs.
CVE-2019-3879 2 Ovirt, Redhat 2 Ovirt, Virtualization 2024-02-28 5.5 MEDIUM 8.1 HIGH
It was discovered that in the ovirt's REST API before version 4.3.2.1, RemoveDiskCommand is triggered as an internal command, meaning the permission validation that should be performed against the calling user is skipped. A user with low privileges (eg Basic Operations) could exploit this flaw to delete disks attached to guests.
CVE-2019-3804 3 Cockpit-project, Fedoraproject, Redhat 3 Cockpit, Fedora, Virtualization 2024-02-28 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-2019-9636 7 Canonical, Debian, Fedoraproject and 4 more 16 Ubuntu Linux, Debian Linux, Fedora and 13 more 2024-02-28 5.0 MEDIUM 9.8 CRITICAL
Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization. The impact is: Information disclosure (credentials, cookies, etc. that are cached against a given hostname). The components are: urllib.parse.urlsplit, urllib.parse.urlparse. The attack vector is: A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed correctly. This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.7, v3.5.8, v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1; v3.7.3, v3.7.3rc1, v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9.
CVE-2019-14835 8 Canonical, Debian, Fedoraproject and 5 more 44 Ubuntu Linux, Debian Linux, Fedora and 41 more 2024-02-28 7.2 HIGH 7.8 HIGH
A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.
