CVE-2021-3656 | 3 Fedoraproject, Linux, Redhat | 31 Fedora, Linux Kernel, 3scale Api Management and 28 more | 2024-11-21 | 8.8 High |
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. | ||||
CVE-2020-25719 | 5 Canonical, Debian, Fedoraproject and 2 more | 18 Ubuntu Linux, Debian Linux, Fedora and 15 more | 2024-11-21 | 7.2 High |
A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise. | ||||
CVE-2020-25717 | 5 Canonical, Debian, Fedoraproject and 2 more | 28 Ubuntu Linux, Debian Linux, Fedora and 25 more | 2024-11-21 | 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-2019-7317 | 11 Canonical, Debian, Hp and 8 more | 35 Ubuntu Linux, Debian Linux, Xp7 Command View and 32 more | 2024-11-21 | 5.3 Medium |
png_image_free in png.c in libpng 1.6.x before 1.6.37 has a use-after-free because png_image_free_function is called under png_safe_execute. | ||||
CVE-2019-6454 | 8 Canonical, Debian, Fedoraproject and 5 more | 26 Ubuntu Linux, Debian Linux, Fedora and 23 more | 2024-11-21 | 5.5 Medium |
An issue was discovered in sd-bus in systemd 239. bus_process_object() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic). | ||||
CVE-2019-14816 | 7 Canonical, Debian, Fedoraproject and 4 more | 60 Ubuntu Linux, Debian Linux, Fedora and 57 more | 2024-11-21 | 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-2018-16881 | 3 Debian, Redhat, Rsyslog | 14 Debian Linux, Enterprise Linux, Enterprise Linux Desktop and 11 more | 2024-11-21 | 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-2017-15129 | 4 Canonical, Fedoraproject, Linux and 1 more | 22 Ubuntu Linux, Fedora, Linux Kernel and 19 more | 2024-11-21 | 4.7 Medium |
A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely. | ||||
CVE-2016-2124 | 5 Canonical, Debian, Fedoraproject and 2 more | 26 Ubuntu Linux, Debian Linux, Fedora and 23 more | 2024-11-21 | 5.9 Medium |
A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to retrieve the plaintext password sent over the wire even if Kerberos authentication was required. |
