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-2018-12398 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2024-02-28 4.3 MEDIUM 6.5 MEDIUM

A vulnerability in unit_deserialize of systemd allows an attacker to supply arbitrary state across systemd re-execution via NotifyAccess. This can be used to improperly influence systemd execution and possibly lead to root privilege escalation. Affected releases are systemd versions up to and including 239.
CVE-2018-1000876 3 Canonical, Gnu, Redhat 5 Ubuntu Linux, Binutils, Enterprise Linux Desktop and 2 more 2024-02-28 4.6 MEDIUM 7.8 HIGH
binutils version 2.32 and earlier contains a Integer Overflow vulnerability in objdump, bfd_get_dynamic_reloc_upper_bound,bfd_canonicalize_dynamic_reloc that can result in Integer overflow trigger heap overflow. Successful exploitation allows execution of arbitrary code.. This attack appear to be exploitable via Local. This vulnerability appears to have been fixed in after commit 3a551c7a1b80fca579461774860574eabfd7f18f.
CVE-2018-5407 7 Canonical, Debian, Nodejs and 4 more 20 Ubuntu Linux, Debian Linux, Node.js and 17 more 2024-02-28 1.9 LOW 4.7 MEDIUM

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-2018-8789 3 Canonical, Debian, Freerdp 3 Ubuntu Linux, Debian Linux, Freerdp 2024-02-28 5.0 MEDIUM 7.5 HIGH
FreeRDP prior to version 2.0.0-rc4 contains several Out-Of-Bounds Reads in the NTLM Authentication module that results in a Denial of Service (segfault).
CVE-2018-16845 5 Apple, Canonical, Debian and 2 more 5 Xcode, Ubuntu Linux, Debian Linux and 2 more 2024-02-28 5.8 MEDIUM 6.1 MEDIUM
nginx before versions 1.15.6, 1.14.1 has a vulnerability in the ngx_http_mp4_module, which might allow an attacker to cause infinite loop in a worker process, cause a worker process crash, or might result in worker process memory disclosure by using a specially crafted mp4 file. The issue only affects nginx if it is built with the ngx_http_mp4_module (the module is not built by default) and the .mp4. directive is used in the configuration file. Further, the attack is only possible if an attacker is able to trigger processing of a specially crafted mp4 file with the ngx_http_mp4_module.
CVE-2018-5738 2 Canonical, Isc 2 Ubuntu Linux, Bind 2024-02-28 5.0 MEDIUM 7.5 HIGH
Change #4777 (introduced in October 2017) introduced an unforeseen issue in releases which were issued after that date, affecting which clients are permitted to make recursive queries to a BIND nameserver. The intended (and documented) behavior is that if an operator has not specified a value for the "allow-recursion" setting, it SHOULD default to one of the following: none, if "recursion no;" is set in named.conf; a value inherited from the "allow-query-cache" or "allow-query" settings IF "recursion yes;" (the default for that setting) AND match lists are explicitly set for "allow-query-cache" or "allow-query" (see the BIND9 Administrative Reference Manual section 6.2 for more details); or the intended default of "allow-recursion {localhost; localnets;};" if "recursion yes;" is in effect and no values are explicitly set for "allow-query-cache" or "allow-query". However, because of the regression introduced by change #4777, it is possible when "recursion yes;" is in effect and no match list values are provided for "allow-query-cache" or "allow-query" for the setting of "allow-recursion" to inherit a setting of all hosts from the "allow-query" setting default, improperly permitting recursion to all clients. Affects BIND 9.9.12, 9.10.7, 9.11.3, 9.12.0->9.12.1-P2, the development release 9.13.0, and also releases 9.9.12-S1, 9.10.7-S1, 9.11.3-S1, and 9.11.3-S2 from BIND 9 Supported Preview Edition.
CVE-2018-15910 5 Artifex, Canonical, Debian and 2 more 9 Ghostscript, Gpl Ghostscript, Ubuntu Linux and 6 more 2024-02-28 6.8 MEDIUM 7.8 HIGH
