The Samba DNS server itself wil

CVE-2021-3697 [HIGH] CWE-787 CVE-2021-3697: A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlle A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlled data to be written in heap. To a successful to be performed the attacker needs to perform some triage over the heap layout and craft an image with a malicious format and payload. This vulnerability can lead to data corruption and eventual code execution

CVE-2021-3975 [MEDIUM] CWE-416 CVE-2021-3975: A use-after-free flaw was found in libvirt. The qemuMonitorUnregister() function in qemuProcessHandl A use-after-free flaw was found in libvirt. The qemuMonitorUnregister() function in qemuProcessHandleMonitorEOF is called using multiple threads without being adequately protected by a monitor lock. This flaw could be triggered by the virConnectGetAllDomainStats API when the guest is shutting down. An unprivileged client with a read-only connection co

CVE-2024-6505 [MEDIUM] CWE-125 CVE-2024-6505: A flaw was found in the virtio-net device in QEMU. When enabling the RSS feature on the virtio-net n A flaw was found in the virtio-net device in QEMU. When enabling the RSS feature on the virtio-net network card, the indirections_table data within RSS becomes controllable. Setting excessively large values may cause an index out-of-bounds issue, potentially resulting in heap overflow access. This flaw allows a privileged user in the guest to crash th

CVE-2021-3667 [MEDIUM] CWE-667 CVE-2021-3667: An improper locking issue was found in the virStoragePoolLookupByTargetPath API of libvirt. It occur An improper locking issue was found in the virStoragePoolLookupByTargetPath API of libvirt. It occurs in the storagePoolLookupByTargetPath function where a locked virStoragePoolObj object is not properly released on ACL permission failure. Clients connecting to the read-write socket with limited ACL permissions could use this flaw to acquire the lock

CVE-2020-15707 [MEDIUM] CWE-362 CVE-2020-15707: Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efili Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. These could be triggered by an extremely large number of arguments to the initrd command
