CVE-2018-12892 2 Debian, Xen 2 Debian Linux, Xen 2024-11-21 N/A
An issue was discovered in Xen 4.7 through 4.10.x. libxl fails to pass the readonly flag to qemu when setting up a SCSI disk, due to what was probably an erroneous merge conflict resolution. Malicious guest administrators or (in some situations) users may be able to write to supposedly read-only disk images. Only emulated SCSI disks (specified as "sd" in the libxl disk configuration, or an equivalent) are affected. IDE disks ("hd") are not affected (because attempts to make them readonly are rejected). Additionally, CDROM devices (that is, devices specified to be presented to the guest as CDROMs, regardless of the nature of the backing storage on the host) are not affected; they are always read only. Only systems using qemu-xen (rather than qemu-xen-traditional) as the device model version are vulnerable. Only systems using libxl or libxl-based toolstacks are vulnerable. (This includes xl, and libvirt with the libxl driver.) The vulnerability is present in Xen versions 4.7 and later. (In earlier versions, provided that the patch for XSA-142 has been applied, attempts to create read only disks are rejected.) If the host and guest together usually support PVHVM, the issue is exploitable only if the malicious guest administrator has control of the guest kernel or guest kernel command line.
CVE-2018-12891 2 Debian, Xen 2 Debian Linux, Xen 2024-11-21 N/A
An issue was discovered in Xen through 4.10.x. Certain PV MMU operations may take a long time to process. For that reason Xen explicitly checks for the need to preempt the current vCPU at certain points. A few rarely taken code paths did bypass such checks. By suitably enforcing the conditions through its own page table contents, a malicious guest may cause such bypasses to be used for an unbounded number of iterations. A malicious or buggy PV guest may cause a Denial of Service (DoS) affecting the entire host. Specifically, it may prevent use of a physical CPU for an indeterminate period of time. All Xen versions from 3.4 onwards are vulnerable. Xen versions 3.3 and earlier are vulnerable to an even wider class of attacks, due to them lacking preemption checks altogether in the affected code paths. Only x86 systems are affected. ARM systems are not affected. Only multi-vCPU x86 PV guests can leverage the vulnerability. x86 HVM or PVH guests as well as x86 single-vCPU PV ones cannot leverage the vulnerability.
CVE-2018-12617 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2024-11-21 7.5 High
qmp_guest_file_read in qga/commands-posix.c and qga/commands-win32.c in qemu-ga (aka QEMU Guest Agent) in QEMU 2.12.50 has an integer overflow causing a g_malloc0() call to trigger a segmentation fault when trying to allocate a large memory chunk. The vulnerability can be exploited by sending a crafted QMP command (including guest-file-read with a large count value) to the agent via the listening socket.
CVE-2018-12601 2 Debian, Sam2p Project 2 Debian Linux, Sam2p 2024-11-21 N/A
There is a heap-based buffer overflow in ReadImage in input-tga.ci in sam2p 0.49.4 that leads to a denial of service or possibly unspecified other impact.

CVE-2018-12565 2 Debian, Linaro 2 Debian Linux, Lava 2024-11-21 8.8 High
An issue was discovered in Linaro LAVA before 2018.5.post1. Because of use of yaml.load() instead of yaml.safe_load() when parsing user data, remote code execution can occur.
CVE-2018-12564 2 Debian, Linaro 2 Debian Linux, Lava 2024-11-21 N/A
An issue was discovered in Linaro LAVA before 2018.5.post1. Because of support for URLs in the submit page, a user can forge an HTTP request that will force lava-server-gunicorn to return any file on the server that is readable by lavaserver and valid yaml.
CVE-2018-12495 2 Debian, Discount Project 2 Debian Linux, Discount 2024-11-21 N/A
The quoteblock function in markdown.c in libmarkdown.a in DISCOUNT 2.2.3a allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted file.
CVE-2018-12458 2 Debian, Ffmpeg 2 Debian Linux, Ffmpeg 2024-11-21 6.5 Medium
An improper integer type in the mpeg4_encode_gop_header function in libavcodec/mpeg4videoenc.c in FFmpeg 2.8 and 4.0 may trigger an assertion violation while converting a crafted AVI file to MPEG4, leading to a denial of service.
CVE-2018-12396 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2024-11-21 N/A
A vulnerability where a WebExtension can run content scripts in disallowed contexts following navigation or other events. This allows for potential privilege escalation by the WebExtension on sites where content scripts should not be run. This vulnerability affects Firefox ESR < 60.3 and Firefox < 63.
CVE-2018-12395 4 Canonical, Debian, Mozilla and 1 more 9 Ubuntu Linux, Debian Linux, Firefox and 6 more 2024-11-21 N/A
By rewriting the Host: request headers using the webRequest API, a WebExtension can bypass domain restrictions through domain fronting. This would allow access to domains that share a host that are otherwise restricted. This vulnerability affects Firefox ESR < 60.3 and Firefox < 63.
CVE-2018-12393 4 Canonical, Debian, Mozilla and 1 more 12 Ubuntu Linux, Debian Linux, Firefox and 9 more 2024-11-21 N/A
A potential vulnerability was found in 32-bit builds where an integer overflow during the conversion of scripts to an internal UTF-16 representation could result in allocating a buffer too small for the conversion. This leads to a possible out-of-bounds write. *Note: 64-bit builds are not vulnerable to this issue.*. This vulnerability affects Firefox < 63, Firefox ESR < 60.3, and Thunderbird < 60.3.
CVE-2018-12385 4 Canonical, Debian, Mozilla and 1 more 12 Ubuntu Linux, Debian Linux, Firefox and 9 more 2024-11-21 N/A
A potentially exploitable crash in TransportSecurityInfo used for SSL can be triggered by data stored in the local cache in the user profile directory. This issue is only exploitable in combination with another vulnerability allowing an attacker to write data into the local cache or from locally installed malware. This issue also triggers a non-exploitable startup crash for users switching between the Nightly and Release versions of Firefox if the same profile is used. This vulnerability affects Thunderbird < 60.2.1, Firefox ESR < 60.2.1, and Firefox < 62.0.2.
CVE-2018-12383 4 Canonical, Debian, Mozilla and 1 more 12 Ubuntu Linux, Debian Linux, Firefox and 9 more 2024-11-21 N/A
If a user saved passwords before Firefox 58 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Firefox 58. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations. This vulnerability affects Firefox < 62, Firefox ESR < 60.2.1, and Thunderbird < 60.2.1.
CVE-2018-12374 4 Canonical, Debian, Mozilla and 1 more 7 Ubuntu Linux, Debian Linux, Thunderbird and 4 more 2024-11-21 N/A
