7.2HighCVE-2018-14665Alpine Linuxalpine · xorg-server +33 morealpine xorg-serverA flaw was found in xorg-x11-server before 1.20.3. An incorrect permission check for -modulepath and -logfile options when starting Xorg. X server allows unprivileged users with the ability to log in to the system via physical console to escalate their privileges and run arbitrary code under root privileges.EPSS27.04%5.5MediumCVE-2018-17972canonical · ubuntu_linux +27 morecanonical ubuntu_linuxAn issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents.EPSS0.36%8.8HighCVE-2018-17466canonical · ubuntu_linux +14 morecanonical ubuntu_linuxIncorrect texture handling in Angle in Google Chrome prior to 70.0.3538.67 allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page.EPSS2.85%9.8CriticalCVE-2018-17456Alpine Linuxalpine · git +69 morealpine gitGit before 2.14.5, 2.15.x before 2.15.3, 2.16.x before 2.16.5, 2.17.x before 2.17.2, 2.18.x before 2.18.1, and 2.19.x before 2.19.1 allows remote code execution during processing of a recursive "git clone" of a superproject if a .gitmodules file has a URL field beginning with a '-' character.EPSS97.36%7.8HighCVE-2018-17183artifex · ghostscript +10 moreartifex ghostscriptArtifex Ghostscript before 9.25 allowed a user-writable error exception table, which could be used by remote attackers able to supply crafted PostScript to potentially overwrite or replace error handlers to inject code.EPSS1.83%8.6HighCVE-2018-17961Alpine Linuxalpine · ghostscript +11 morealpine ghostscriptArtifex Ghostscript 9.25 and earlier allows attackers to bypass a sandbox protection mechanism via vectors involving errorhandler setup. NOTE: this issue exists because of an incomplete fix for CVE-2018-17183.EPSS9.98%9.8CriticalCVE-2018-7750Alpine Linuxalpine · py3-paramiko +23 morealpine py3-paramikotransport.py in the SSH server implementation of Paramiko before 1.17.6, 1.18.x before 1.18.5, 2.0.x before 2.0.8, 2.1.x before 2.1.5, 2.2.x before 2.2.3, 2.3.x before 2.3.2, and 2.4.x before 2.4.1 does not properly check whether authentication is completed before processing other requests, as demonstrated by channel-open. A customized SSH client can simply skip the authentication step.EPSS27.11%8.8HighCVE-2018-7550canonical · ubuntu_linux +11 morecanonical ubuntu_linuxThe load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access.EPSS0.61%7.8HighCVE-2018-7566canonical · ubuntu_linux +36 morecanonical ubuntu_linuxThe Linux kernel 4.15 has a Buffer Overflow via an SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to /dev/snd/seq by a local user.EPSS0.47%9.8CriticalCVE-2018-7225Alpine Linuxalpine · libvncserver +24 morealpine libvncserverAn 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.EPSS6.11%5.5MediumCVE-2018-7858canonical · ubuntu_linux +15 morecanonical ubuntu_linuxQuick Emulator (aka QEMU), when built with the Cirrus CLGD 54xx VGA Emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds access and QEMU process crash) by leveraging incorrect region calculation when updating VGA display.EPSS0.61%10CriticalCVE-2018-18505canonical · ubuntu_linux +16 morecanonical ubuntu_linuxAn earlier fix for an Inter-process Communication (IPC) vulnerability, CVE-2011-3079, added authentication to communication between IPC endpoints and server parents during IPC process creation. This authentication is insufficient for channels created after the IPC process is started, leading to the authentication not being correctly applied to later channels. This could allow for a sandbox escape through IPC channels due to lack of message validation in the listener process. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65.EPSS4.42%8.8HighCVE-2018-18356canonical · ubuntu_linux +15 morecanonical ubuntu_linuxAn integer overflow in path handling lead to a use after free in Skia in Google Chrome prior to 71.0.3578.80 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.EPSS3.28%6.5MediumCVE-2018-18494canonical · ubuntu_linux +14 morecanonical ubuntu_linuxA same-origin policy violation allowing the theft of cross-origin URL entries when using the Javascript location property to cause a redirection to another site using performance.getEntries(). This is a same-origin policy violation and could allow for data theft. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64.EPSS1.55%9.8CriticalCVE-2018-18493canonical · ubuntu_linux +14 morecanonical ubuntu_linuxA buffer overflow can occur in the Skia library during buffer offset calculations with hardware accelerated canvas 2D actions due to the use of 32-bit calculations instead of 64-bit. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64.EPSS4.98%6.5MediumCVE-2018-18897canonical · ubuntu_linux +11 morecanonical ubuntu_linuxAn issue was discovered in Poppler 0.71.0. There is a memory leak in GfxColorSpace::setDisplayProfile in GfxState.cc, as demonstrated by pdftocairo.EPSS1.96%8.6HighCVE-2018-18284Alpine Linuxalpine · ghostscript +13 morealpine ghostscriptArtifex Ghostscript 9.25 and earlier allows attackers to bypass a sandbox protection mechanism via vectors involving the 1Policy operator.EPSS16.29%9.8CriticalCVE-2018-18492canonical · ubuntu_linux +14 morecanonical ubuntu_linuxA use-after-free vulnerability can occur after deleting a selection element due to a weak reference to the select element in the options collection. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64.EPSS9.65%6.3MediumCVE-2018-18073Alpine Linuxalpine · ghostscript +11 morealpine ghostscriptArtifex Ghostscript allows attackers to bypass a sandbox protection mechanism by leveraging exposure of system operators in the saved execution stack in an error object.EPSS2.73%5.5MediumCVE-2018-18397canonical · ubuntu_linux +46 morecanonical ubuntu_linuxThe userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c.EPSS0.51%
