CVE-2018-17100 3 Canonical, Debian, Libtiff 3 Ubuntu Linux, Debian Linux, Libtiff 2024-11-21 6.8 MEDIUM 8.8 HIGH
An issue was discovered in LibTIFF 4.0.9. There is a int32 overflow in multiply_ms in tools/ppm2tiff.c, which can cause a denial of service (crash) or possibly have unspecified other impact via a crafted image file.
CVE-2018-17095 2 Audio File Library Project, Canonical 2 Audio File Library, Ubuntu Linux 2024-11-21 6.8 MEDIUM 8.8 HIGH
An issue has been discovered in mpruett Audio File Library (aka audiofile) 0.3.6, 0.3.5, 0.3.4, 0.3.3, 0.3.2, 0.3.1, 0.3.0. A heap-based buffer overflow in Expand3To4Module::run has occurred when running sfconvert.
CVE-2018-17000 3 Canonical, Debian, Libtiff 3 Ubuntu Linux, Debian Linux, Libtiff 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
A NULL pointer dereference in the function _TIFFmemcmp at tif_unix.c (called from TIFFWriteDirectoryTagTransferfunction) in LibTIFF 4.0.9 allows an attacker to cause a denial-of-service through a crafted tiff file. This vulnerability can be triggered by the executable tiffcp.
CVE-2018-16890 8 Canonical, Debian, F5 and 5 more 10 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 7 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds.
CVE-2018-16888 4 Canonical, Netapp, Redhat and 1 more 5 Ubuntu Linux, Active Iq Performance Analytics Services, Element Software and 2 more 2024-11-21 1.9 LOW 4.7 MEDIUM
It was discovered systemd does not correctly check the content of PIDFile files before using it to kill processes. When a service is run from an unprivileged user (e.g. User field set in the service file), a local attacker who is able to write to the PIDFile of the mentioned service may use this flaw to trick systemd into killing other services and/or privileged processes. Versions before v237 are vulnerable.
CVE-2018-16884 4 Canonical, Debian, Linux and 1 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2024-11-21 6.7 MEDIUM 8.0 HIGH
A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.
CVE-2018-16882 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2024-11-21 7.2 HIGH 8.8 HIGH
A use-after-free issue was found in the way the Linux kernel's KVM hypervisor processed posted interrupts when nested(=1) virtualization is enabled. In nested_get_vmcs12_pages(), in case of an error while processing posted interrupt address, it unmaps the 'pi_desc_page' without resetting 'pi_desc' descriptor address, which is later used in pi_test_and_clear_on(). A guest user/process could use this flaw to crash the host kernel resulting in DoS or potentially gain privileged access to a system. Kernel versions before 4.14.91 and before 4.19.13 are vulnerable.
CVE-2018-16880 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2024-11-21 6.9 MEDIUM 7.0 HIGH
A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest, under specific conditions, can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. Versions from v4.16 and newer are vulnerable.
CVE-2018-16878 6 Canonical, Clusterlabs, Debian and 3 more 9 Ubuntu Linux, Pacemaker, Debian Linux and 6 more 2024-11-21 2.1 LOW 5.5 MEDIUM
A flaw was found in pacemaker up to and including version 2.0.1. An insufficient verification inflicted preference of uncontrolled processes can lead to DoS
CVE-2018-16877 6 Canonical, Clusterlabs, Debian and 3 more 9 Ubuntu Linux, Pacemaker, Debian Linux and 6 more 2024-11-21 4.6 MEDIUM 7.8 HIGH
A flaw was found in the way pacemaker's client-server authentication was implemented in versions up to and including 2.0.0. A local attacker could use this flaw, and combine it with other IPC weaknesses, to achieve local privilege escalation.
CVE-2018-16876 4 Canonical, Debian, Redhat and 1 more 10 Ubuntu Linux, Debian Linux, Ansible and 7 more 2024-11-21 3.5 LOW 5.3 MEDIUM
ansible before versions 2.5.14, 2.6.11, 2.7.5 is vulnerable to a information disclosure flaw in vvv+ mode with no_log on that can lead to leakage of sensible data.
CVE-2018-16872 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2024-11-21 3.5 LOW 5.3 MEDIUM
A flaw was found in qemu Media Transfer Protocol (MTP). The code opening files in usb_mtp_get_object and usb_mtp_get_partial_object and directories in usb_mtp_object_readdir doesn't consider that the underlying filesystem may have changed since the time lstat(2) was called in usb_mtp_object_alloc, a classical TOCTTOU problem. An attacker with write access to the host filesystem shared with a guest can use this property to navigate the host filesystem in the context of the QEMU process and read any file the QEMU process has access to. Access to the filesystem may be local or via a network share protocol such as CIFS.
CVE-2018-16867 3 Canonical, Fedoraproject, Qemu 3 Ubuntu Linux, Fedora, Qemu 2024-11-21 4.4 MEDIUM 7.8 HIGH
A flaw was found in qemu Media Transfer Protocol (MTP) before version 3.1.0. A path traversal in the in usb_mtp_write_data function in hw/usb/dev-mtp.c due to an improper filename sanitization. When the guest device is mounted in read-write mode, this allows to read/write arbitrary files which may lead do DoS scenario OR possibly lead to code execution on the host.
CVE-2018-16866 5 Canonical, Debian, Netapp and 2 more 21 Ubuntu Linux, Debian Linux, Active Iq Performance Analytics Services and 18 more 2024-11-21 2.1 LOW 3.3 LOW
An out of bounds read was discovered in systemd-journald in the way it parses log messages that terminate with a colon ':'. A local attacker can use this flaw to disclose process memory data. Versions from v221 to v239 are vulnerable.
CVE-2018-16865 5 Canonical, Debian, Oracle and 2 more 11 Ubuntu Linux, Debian Linux, Communications Session Border Controller and 8 more 2024-11-21 4.6 MEDIUM 7.8 HIGH
An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when many entries are sent to the journal socket. A local attacker, or a remote one if systemd-journal-remote is used, may use this flaw to crash systemd-journald or execute code with journald privileges. Versions through v240 are vulnerable.
CVE-2018-16864 5 Canonical, Debian, Oracle and 2 more 11 Ubuntu Linux, Debian Linux, Communications Session Border Controller and 8 more 2024-11-21 4.6 MEDIUM 7.8 HIGH
An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when a program with long command line arguments calls syslog. A local attacker may use this flaw to crash systemd-journald or escalate his privileges. Versions through v240 are vulnerable.
CVE-2018-16862 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2024-11-21 2.1 LOW 5.3 MEDIUM
A security flaw was found in the Linux kernel in a way that the cleancache subsystem clears an inode after the final file truncation (removal). The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one.
CVE-2018-16851 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
Samba from version 4.0.0 and before versions 4.7.12, 4.8.7, 4.9.3 is vulnerable to a denial of service. During the processing of an LDAP search before Samba's AD DC returns the LDAP entries to the client, the entries are cached in a single memory object with a maximum size of 256MB. When this size is reached, the Samba process providing the LDAP service will follow the NULL pointer, terminating the process. There is no further vulnerability associated with this issue, merely a denial of service.
CVE-2018-16850 3 Canonical, Postgresql, Redhat 3 Ubuntu Linux, Postgresql, Enterprise Linux 2024-11-21 7.5 HIGH 9.8 CRITICAL
postgresql before versions 11.1, 10.6 is vulnerable to a to SQL injection in pg_upgrade and pg_dump via CREATE TRIGGER ... REFERENCING. Using a purpose-crafted trigger definition, an attacker can cause arbitrary SQL statements to run, with superuser privileges.
CVE-2018-16847 2 Canonical, Qemu 2 Ubuntu Linux, Qemu 2024-11-21 4.6 MEDIUM 7.8 HIGH
An OOB heap buffer r/w access issue was found in the NVM Express Controller emulation in QEMU. It could occur in nvme_cmb_ops routines in nvme device. A guest user/process could use this flaw to crash the QEMU process resulting in DoS or potentially run arbitrary code with privileges of the QEMU process.
