CVE-2017-18273 3 Canonical, Debian, Imagemagick 3 Ubuntu Linux, Debian Linux, Imagemagick 2024-02-28 7.1 HIGH 6.5 MEDIUM
In ImageMagick 7.0.7-16 Q16 x86_64 2017-12-22, an infinite loop vulnerability was found in the function ReadTXTImage in coders/txt.c, which allows attackers to cause a denial of service (CPU exhaustion) via a crafted image file that is mishandled in a GetImageIndexInList call.
CVE-2018-8779 3 Canonical, Debian, Ruby-lang 3 Ubuntu Linux, Debian Linux, Ruby 2024-02-28 5.0 MEDIUM 7.5 HIGH
In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, the UNIXServer.open and UNIXSocket.open methods are not checked for null characters. It may be connected to an unintended socket.
CVE-2018-9240 3 Canonical, Debian, Ncmpc Project 3 Ubuntu Linux, Debian Linux, Ncmpc 2024-02-28 5.0 MEDIUM 7.5 HIGH
ncmpc through 0.29 is prone to a NULL pointer dereference flaw. If a user uses the chat screen and another client sends a long chat message, a crash and denial of service could occur.
CVE-2018-0732 4 Canonical, Debian, Nodejs and 1 more 4 Ubuntu Linux, Debian Linux, Node.js and 1 more 2024-02-28 5.0 MEDIUM 7.5 HIGH
During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This could be exploited in a Denial Of Service attack. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev (Affected 1.0.2-1.0.2o).
CVE-2018-1057 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2024-02-28 6.5 MEDIUM 8.8 HIGH
On a Samba 4 AD DC the LDAP server in all versions of Samba from 4.0.0 onwards incorrectly validates permissions to modify passwords over LDAP allowing authenticated users to change any other users' passwords, including administrative users and privileged service accounts (eg Domain Controllers).
CVE-2018-7225 4 Canonical, Debian, Libvncserver Project and 1 more 9 Ubuntu Linux, Debian Linux, Libvncserver and 6 more 2024-02-28 7.5 HIGH 9.8 CRITICAL
An issue was discovered in LibVNCServer through 0.9.11. rfbProcessClientNormalMessage() in rfbserver.c does not sanitize msg.cct.length, leading to access to uninitialized and potentially sensitive data or possibly unspecified other impact (e.g., an integer overflow) via specially crafted VNC packets.
CVE-2017-18190 3 Apple, Canonical, Debian 3 Cups, Ubuntu Linux, Debian Linux 2024-02-28 5.0 MEDIUM 7.5 HIGH
A localhost.localdomain whitelist entry in valid_host() in scheduler/client.c in CUPS before 2.2.2 allows remote attackers to execute arbitrary IPP commands by sending POST requests to the CUPS daemon in conjunction with DNS rebinding. The localhost.localdomain name is often resolved via a DNS server (neither the OS nor the web browser is responsible for ensuring that localhost.localdomain is 127.0.0.1).
CVE-2017-18075 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2024-02-28 7.2 HIGH 7.8 HIGH
crypto/pcrypt.c in the Linux kernel before 4.14.13 mishandles freeing instances, allowing a local user able to access the AF_ALG-based AEAD interface (CONFIG_CRYPTO_USER_API_AEAD) and pcrypt (CONFIG_CRYPTO_PCRYPT) to cause a denial of service (kfree of an incorrect pointer) or possibly have unspecified other impact by executing a crafted sequence of system calls.
CVE-2018-10323 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-02-28 4.9 MEDIUM 5.5 MEDIUM
The xfs_bmap_extents_to_btree function in fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through 4.16.3 allows local users to cause a denial of service (xfs_bmapi_write NULL pointer dereference) via a crafted xfs image.
CVE-2017-14177 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2024-02-28 7.2 HIGH 7.8 HIGH
Apport through 2.20.7 does not properly handle core dumps from setuid binaries allowing local users to create certain files as root which an attacker could leverage to perform a denial of service via resource exhaustion or possibly gain root privileges. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1324.
CVE-2018-1106 4 Canonical, Debian, Packagekit Project and 1 more 9 Ubuntu Linux, Debian Linux, Packagekit and 6 more 2024-02-28 2.1 LOW 5.5 MEDIUM
An authentication bypass flaw has been found in PackageKit before 1.1.10 that allows users without administrator privileges to install signed packages. A local attacker can use this vulnerability to install vulnerable packages to further compromise a system.
CVE-2018-1000005 3 Canonical, Debian, Haxx 3 Ubuntu Linux, Debian Linux, Libcurl 2024-02-28 6.4 MEDIUM 9.1 CRITICAL
libcurl 7.49.0 to and including 7.57.0 contains an out bounds read in code handling HTTP/2 trailers. It was reported (https://github.com/curl/curl/pull/2231) that reading an HTTP/2 trailer could mess up future trailers since the stored size was one byte less than required. The problem is that the code that creates HTTP/1-like headers from the HTTP/2 trailer data once appended a string like `:` to the target buffer, while this was recently changed to `: ` (a space was added after the colon) but the following math wasn't updated correspondingly. When accessed, the data is read out of bounds and causes either a crash or that the (too large) data gets passed to client write. This could lead to a denial-of-service situation or an information disclosure if someone has a service that echoes back or uses the trailers for something.
CVE-2018-4101 4 Apple, Canonical, Microsoft and 1 more 8 Icloud, Iphone Os, Itunes and 5 more 2024-02-28 6.8 MEDIUM 8.8 HIGH
An issue was discovered in certain Apple products. iOS before 11.3 is affected. Safari before 11.1 is affected. iCloud before 7.4 on Windows is affected. iTunes before 12.7.4 on Windows is affected. tvOS before 11.3 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.
CVE-2018-1108 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-02-28 4.3 MEDIUM 5.9 MEDIUM
kernel drivers before version 4.17-rc1 are vulnerable to a weakness in the Linux kernel's implementation of random seed data. Programs, early in the boot sequence, could use the data allocated for the seed before it was sufficiently generated.
CVE-2018-12928 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2024-02-28 4.9 MEDIUM 5.5 MEDIUM
In the Linux kernel 4.15.0, a NULL pointer dereference was discovered in hfs_ext_read_extent in hfs.ko. This can occur during a mount of a crafted hfs filesystem.
CVE-2018-5381 4 Canonical, Debian, Quagga and 1 more 5 Ubuntu Linux, Debian Linux, Quagga and 2 more 2024-02-28 5.0 MEDIUM 7.5 HIGH
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-2018-13005 3 Canonical, Debian, Gpac 3 Ubuntu Linux, Debian Linux, Gpac 2024-02-28 7.5 HIGH 9.8 CRITICAL
An issue was discovered in MP4Box in GPAC 0.7.1. The function urn_Read in isomedia/box_code_base.c has a heap-based buffer over-read.
CVE-2018-4129 4 Apple, Canonical, Microsoft and 1 more 9 Icloud, Iphone Os, Itunes and 6 more 2024-02-28 6.8 MEDIUM 8.8 HIGH
An issue was discovered in certain Apple products. iOS before 11.3 is affected. Safari before 11.1 is affected. iCloud before 7.4 on Windows is affected. iTunes before 12.7.4 on Windows is affected. tvOS before 11.3 is affected. watchOS before 4.3 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.
CVE-2018-5380 4 Canonical, Debian, Quagga and 1 more 5 Ubuntu Linux, Debian Linux, Quagga and 2 more 2024-02-28 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-2018-2780 2 Canonical, Oracle 2 Ubuntu Linux, Mysql 2024-02-28 4.0 MEDIUM 6.5 MEDIUM
Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Optimizer). Supported versions that are affected are 5.7.21 and prior.
