CVE-2021-4093 4 Canonical, Fedoraproject, Linux and 1 more 4 Ubuntu Linux, Fedora, Linux Kernel and 1 more 2023-01-19 7.2 HIGH 8.8 HIGH
A flaw was found in the KVM's AMD code for supporting the Secure Encrypted Virtualization-Encrypted State (SEV-ES). A KVM guest using SEV-ES can trigger out-of-bounds reads and writes in the host kernel via a malicious VMGEXIT for a string I/O instruction (for example, outs or ins) using the exit reason SVM_EXIT_IOIO. This issue results in a crash of the entire system or a potential guest-to-host escape scenario.
CVE-2017-16995 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2023-01-19 7.2 HIGH 7.8 HIGH
The check_alu_op function in kernel/bpf/verifier.c in the Linux kernel through 4.4 allows local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging incorrect sign extension.
CVE-2017-11473 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2023-01-19 7.2 HIGH 7.8 HIGH
Buffer overflow in the mp_override_legacy_irq() function in arch/x86/kernel/acpi/boot.c in the Linux kernel through 3.2 allows local users to gain privileges via a crafted ACPI table.
CVE-2019-16935 3 Canonical, Debian, Python 3 Ubuntu Linux, Debian Linux, Python 2023-01-19 4.3 MEDIUM 6.1 MEDIUM
The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has XSS via the server_title field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in Lib/xmlrpc/server.py in Python 3.x. If set_server_title is called with untrusted input, arbitrary JavaScript can be delivered to clients that visit the http URL for this server.
CVE-2017-15115 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2023-01-19 7.2 HIGH 7.8 HIGH
The sctp_do_peeloff function in net/sctp/socket.c in the Linux kernel before 4.14 does not check whether the intended netns is used in a peel-off action, which allows local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via crafted system calls.
CVE-2017-16526 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2023-01-19 7.2 HIGH 7.8 HIGH
drivers/uwb/uwbd.c in the Linux kernel before 4.13.6 allows local users to cause a denial of service (general protection fault and system crash) or possibly have unspecified other impact via a crafted USB device.
CVE-2017-15868 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2023-01-19 7.2 HIGH 7.8 HIGH
The bnep_add_connection function in net/bluetooth/bnep/core.c in the Linux kernel before 3.19 does not ensure that an l2cap socket is available, which allows local users to gain privileges via a crafted application.
CVE-2017-17805 6 Canonical, Debian, Linux and 3 more 8 Ubuntu Linux, Debian Linux, Linux Kernel and 5 more 2023-01-19 7.2 HIGH 7.8 HIGH
The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel crash) or have unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable.
CVE-2018-6557 2 Base-files Project, Canonical 2 Base-files, Ubuntu Linux 2023-01-18 4.4 MEDIUM 7.0 HIGH
The MOTD update script in the base-files package in Ubuntu 18.04 LTS before 10.1ubuntu2.2, and Ubuntu 18.10 before 10.1ubuntu6 incorrectly handled temporary files. A local attacker could use this issue to cause a denial of service, or possibly escalate privileges if kernel symlink restrictions were disabled.
CVE-2019-14494 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-01-18 4.3 MEDIUM 7.5 HIGH
An issue was discovered in Poppler through 0.78.0. There is a divide-by-zero error in the function SplashOutputDev::tilingPatternFill at SplashOutputDev.cc.
CVE-2013-1059 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2023-01-17 7.8 HIGH N/A
net/ceph/auth_none.c in the Linux kernel through 3.10 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via an auth_reply message that triggers an attempted build_request operation.
CVE-2014-6416 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2023-01-17 7.8 HIGH N/A
Buffer overflow in net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, allows remote attackers to cause a denial of service (memory corruption and panic) or possibly have unspecified other impact via a long unencrypted auth ticket.
CVE-2014-7145 3 Canonical, Linux, Redhat 6 Ubuntu Linux, Linux Kernel, Enterprise Linux Desktop and 3 more 2023-01-17 7.8 HIGH N/A
The SMB2_tcon function in fs/cifs/smb2pdu.c in the Linux kernel before 3.16.3 allows remote CIFS servers to cause a denial of service (NULL pointer dereference and client system crash) or possibly have unspecified other impact by deleting the IPC$ share during resolution of DFS referrals.
CVE-2016-3135 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2023-01-17 7.2 HIGH 7.8 HIGH
Integer overflow in the xt_alloc_table_info function in net/netfilter/x_tables.c in the Linux kernel through 4.5.2 on 32-bit platforms allows local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call.

CVE-2016-1583 4 Canonical, Debian, Linux and 1 more 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more 2023-01-17 7.2 HIGH 7.8 HIGH
The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3 allows local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling.
