Linux kernel vhost since version 4.8 does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file.
CVE-2018-1087 4 Canonical, Debian, Linux and 1 more 11 Ubuntu Linux, Debian Linux, Linux Kernel and 8 more 2019-10-09 4.6 MEDIUM 7.8 HIGH
kernel KVM before versions kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 and kernel 4.17-rc3 is vulnerable to a flaw in the way the Linux kernel's KVM hypervisor handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and exceptions, rather they are delivered once the first instruction after the stack switch is executed. An unprivileged KVM guest user could use this flaw to crash the guest or, potentially, escalate their privileges in the guest.
CVE-2018-1130 4 Canonical, Debian, Linux and 1 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2019-10-09 4.9 MEDIUM 5.5 MEDIUM
Linux kernel before version 4.16-rc7 is vulnerable to a null pointer dereference in dccp_write_xmit() function in net/dccp/output.c in that allows a local user to cause a denial of service by a number of certain crafted system calls.
CVE-2018-1053 4 Canonical, Debian, Postgresql and 1 more 4 Ubuntu Linux, Debian Linux, Postgresql and 1 more 2019-10-09 3.3 LOW 7.0 HIGH
In postgresql 9.3.x before 9.3.21, 9.4.x before 9.4.16, 9.5.x before 9.5.11, 9.6.x before 9.6.7 and 10.x before 10.2, pg_upgrade creates file in current working directory containing the output of `pg_dumpall -g` under umask which was in effect when the user invoked pg_upgrade, and not under 0077 which is normally used for other temporary files. This can allow an authenticated attacker to read or modify the one file, which may contain encrypted or unencrypted database passwords. The attack is infeasible if a directory mode blocks the attacker searching the current working directory or if the prevailing umask blocks the attacker opening the file.
CVE-2018-1120 4 Canonical, Debian, Linux and 1 more 7 Ubuntu Linux, Debian Linux, Linux Kernel and 4 more 2019-10-09 3.5 LOW 5.3 MEDIUM
A flaw was found affecting the Linux kernel before version 4.17. By mmap()ing a FUSE-backed file onto a process's memory containing command line arguments (or environment strings), an attacker can cause utilities from psutils or procps (such as ps, w) or any other program which makes a read() call to the /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some controlled time (as a synchronization primitive for other attacks).
CVE-2018-1058 3 Canonical, Postgresql, Redhat 3 Ubuntu Linux, Postgresql, Cloudforms 2019-10-09 6.5 MEDIUM 8.8 HIGH
A flaw was found in the way Postgresql allowed a user to modify the behavior of a query for other users. An attacker with a user account could use this flaw to execute code with the permissions of superuser in the database. Versions 9.3 through 10 are affected.
CVE-2018-16839 3 Canonical, Debian, Haxx 3 Ubuntu Linux, Debian Linux, Curl 2019-10-09 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-2018-16841 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2019-10-09 4.0 MEDIUM 6.5 MEDIUM
Samba from version 4.3.0 and before versions 4.7.12, 4.8.7 and 4.9.3 are vulnerable to a denial of service. When configured to accept smart-card authentication, Samba's KDC will call talloc_free() twice on the same memory if the principal in a validly signed certificate does not match the principal in the AS-REQ. This is only possible after authentication with a trusted certificate. talloc is robust against further corruption from a double-free with talloc_free() and directly calls abort(), terminating the KDC process.
CVE-2018-16840 2 Canonical, Haxx 2 Ubuntu Linux, Curl 2019-10-09 7.5 HIGH 9.8 CRITICAL
A heap use-after-free flaw was found in curl versions from 7.59.0 through 7.61.1 in the code related to closing an easy handle. When closing and cleaning up an 'easy' handle in the `Curl_close()` function, the library code first frees a struct (without nulling the pointer) and might then subsequently erroneously write to a struct field within that already freed struct.
CVE-2018-16882 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2019-10-09 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-2018-16851 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2019-10-09 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-2018-14629 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2019-10-09 4.0 MEDIUM 6.5 MEDIUM
A denial of service vulnerability was discovered in Samba's LDAP server before versions 4.7.12, 4.8.7, and 4.9.3. A CNAME loop could lead to infinite recursion in the server. An unprivileged local attacker could create such an entry, leading to denial of service.
CVE-2018-15378 3 Canonical, Clamav, Debian 3 Ubuntu Linux, Clamav, Debian Linux 2019-10-09 4.3 MEDIUM 5.5 MEDIUM
A vulnerability in ClamAV versions prior to 0.100.2 could allow an attacker to cause a denial of service (DoS) condition. The vulnerability is due to an error related to the MEW unpacker within the "unmew11()" function (libclamav/mew.c), which can be exploited to trigger an invalid read memory access via a specially crafted EXE file.
CVE-2018-10881 4 Canonical, Debian, Linux and 1 more 8 Ubuntu Linux, Debian Linux, Linux Kernel and 5 more 2019-10-09 4.9 MEDIUM 5.5 MEDIUM

A bug in Bluez may allow for the Bluetooth Discoverable state being set to on when no Bluetooth agent is registered with the system. This situation could lead to the unauthorized pairing of certain Bluetooth devices without any form of authentication. Versions before bluez 5.51 are vulnerable.
CVE-2017-7526 3 Canonical, Debian, Gnupg 3 Ubuntu Linux, Debian Linux, Libgcrypt 2019-10-09 4.3 MEDIUM 6.8 MEDIUM
libgcrypt before version 1.7.8 is vulnerable to a cache side-channel attack resulting into a complete break of RSA-1024 while using the left-to-right method for computing the sliding-window expansion. The same attack is believed to work on RSA-2048 with moderately more computation. This side-channel requires that attacker can run arbitrary software on the hardware where the private RSA key is used.
CVE-2017-7518 4 Canonical, Debian, Linux and 1 more 9 Ubuntu Linux, Debian Linux, Linux Kernel and 6 more 2019-10-09 4.6 MEDIUM 7.8 HIGH
A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB) being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges inside the guest. Linux guests are not affected by this.
