CVE-2018-5764 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Rsync 2024-11-21 5.0 MEDIUM 7.5 HIGH
The parse_arguments function in options.c in rsyncd in rsync before 3.1.3 does not prevent multiple --protect-args uses, which allows remote attackers to bypass an argument-sanitization protection mechanism.
CVE-2018-5750 4 Canonical, Debian, Linux and 1 more 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more 2024-11-21 2.1 LOW 5.5 MEDIUM
The acpi_smbus_hc_add function in drivers/acpi/sbshc.c in the Linux kernel through 4.14.15 allows local users to obtain sensitive address information by reading dmesg data from an SBS HC printk call.
CVE-2018-5740 7 Canonical, Debian, Hp and 4 more 11 Ubuntu Linux, Debian Linux, Hp-ux and 8 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
"deny-answer-aliases" is a little-used feature intended to help recursive server operators protect end users against DNS rebinding attacks, a potential method of circumventing the security model used by client browsers. However, a defect in this feature makes it easy, when the feature is in use, to experience an assertion failure in name.c. Affects BIND 9.7.0->9.8.8, 9.9.0->9.9.13, 9.10.0->9.10.8, 9.11.0->9.11.4, 9.12.0->9.12.2, 9.13.0->9.13.2.
CVE-2018-5738 2 Canonical, Isc 2 Ubuntu Linux, Bind 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
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-2018-5712 3 Canonical, Debian, Php 3 Ubuntu Linux, Debian Linux, Php 2024-11-21 4.3 MEDIUM 6.1 MEDIUM
An issue was discovered in PHP before 5.6.33, 7.0.x before 7.0.27, 7.1.x before 7.1.13, and 7.2.x before 7.2.1. There is Reflected XSS on the PHAR 404 error page via the URI of a request for a .phar file.
CVE-2018-5711 3 Canonical, Debian, Php 3 Ubuntu Linux, Debian Linux, Php 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
gd_gif_in.c in the GD Graphics Library (aka libgd), as used in PHP before 5.6.33, 7.0.x before 7.0.27, 7.1.x before 7.1.13, and 7.2.x before 7.2.1, has an integer signedness error that leads to an infinite loop via a crafted GIF file, as demonstrated by a call to the imagecreatefromgif or imagecreatefromstring PHP function. This is related to GetCode_ and gdImageCreateFromGifCtx.
CVE-2018-5683 4 Canonical, Debian, Qemu and 1 more 9 Ubuntu Linux, Debian Linux, Qemu and 6 more 2024-11-21 2.1 LOW 6.0 MEDIUM
The vga_draw_text function in Qemu allows local OS guest privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) by leveraging improper memory address validation.
CVE-2018-5407 7 Canonical, Debian, Nodejs and 4 more 20 Ubuntu Linux, Debian Linux, Node.js and 17 more 2024-11-21 1.9 LOW 4.7 MEDIUM
Simultaneous Multi-threading (SMT) in processors can enable local users to exploit software vulnerable to timing attacks via a side-channel timing attack on 'port contention'.
CVE-2018-5391 7 Canonical, Debian, F5 and 4 more 73 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 70 more 2024-11-21 7.8 HIGH 7.5 HIGH
The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size.
CVE-2018-5390 8 A10networks, Canonical, Cisco and 5 more 40 Advanced Core Operating System, Ubuntu Linux, Collaboration Meeting Rooms and 37 more 2024-11-21 7.8 HIGH 7.5 HIGH
Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service.
CVE-2018-5388 3 Canonical, Debian, Strongswan 3 Ubuntu Linux, Debian Linux, Strongswan 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
In stroke_socket.c in strongSwan before 5.6.3, a missing packet length check could allow a buffer underflow, which may lead to resource exhaustion and denial of service while reading from the socket.
CVE-2018-5381 4 Canonical, Debian, Quagga and 1 more 5 Ubuntu Linux, Debian Linux, Quagga and 2 more 2024-11-21 5.0 MEDIUM 6.5 MEDIUM
The Quagga BGP daemon (bgpd) prior to version 1.2.3 has a bug in its parsing of "Capabilities" in BGP OPEN messages, in the bgp_packet.c:bgp_capability_msg_parse function. The parser can enter an infinite loop on invalid capabilities if a Multi-Protocol capability does not have a recognized AFI/SAFI, causing a denial of service.
CVE-2018-5380 4 Canonical, Debian, Quagga and 1 more 5 Ubuntu Linux, Debian Linux, Quagga and 2 more 2024-11-21 4.0 MEDIUM 4.3 MEDIUM
The Quagga BGP daemon (bgpd) prior to version 1.2.3 can overrun internal BGP code-to-string conversion tables used for debug by 1 pointer value, based on input.
CVE-2018-5379 5 Canonical, Debian, Quagga and 2 more 10 Ubuntu Linux, Debian Linux, Quagga and 7 more 2024-11-21 7.5 HIGH 7.5 HIGH
The Quagga BGP daemon (bgpd) prior to version 1.2.3 can double-free memory when processing certain forms of UPDATE message, containing cluster-list and/or unknown attributes. A successful attack could cause a denial of service or potentially allow an attacker to execute arbitrary code.
CVE-2018-5378 3 Canonical, Debian, Quagga 3 Ubuntu Linux, Debian Linux, Quagga 2024-11-21 4.9 MEDIUM 7.1 HIGH
The Quagga BGP daemon (bgpd) prior to version 1.2.3 does not properly bounds check the data sent with a NOTIFY to a peer, if an attribute length is invalid. Arbitrary data from the bgpd process may be sent over the network to a peer and/or bgpd may crash.
CVE-2018-5358 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
ImageMagick 7.0.7-22 Q16 has memory leaks in the EncodeImageAttributes function in coders/json.c, as demonstrated by the ReadPSDLayersInternal function in coders/psd.c.
CVE-2018-5357 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
ImageMagick 7.0.7-22 Q16 has memory leaks in the ReadDCMImage function in coders/dcm.c.
CVE-2018-5345 5 Canonical, Debian, Fedoraproject and 2 more 10 Ubuntu Linux, Debian Linux, Fedora and 7 more 2024-11-21 6.8 MEDIUM 7.8 HIGH
A stack-based buffer overflow within GNOME gcab through 0.7.4 can be exploited by malicious attackers to cause a crash or, potentially, execute arbitrary code via a crafted .cab file.
CVE-2018-5344 3 Canonical, Linux, Redhat 6 Ubuntu Linux, Linux Kernel, Enterprise Linux Desktop and 3 more 2024-11-21 4.6 MEDIUM 7.8 HIGH
In the Linux kernel through 4.14.13, drivers/block/loop.c mishandles lo_release serialization, which allows attackers to cause a denial of service (__lock_acquire use-after-free) or possibly have unspecified other impact.
CVE-2018-5333 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
In the Linux kernel through 4.14.13, the rds_cmsg_atomic function in net/rds/rdma.c mishandles cases where page pinning fails or an invalid address is supplied, leading to an rds_atomic_free_op NULL pointer dereference.
