CVE-2018-1000030 2 Canonical, Python 2 Ubuntu Linux, Python 2020-08-24 3.3 LOW 3.6 LOW
Python 2.7.14 is vulnerable to a Heap-Buffer-Overflow as well as a Heap-Use-After-Free. Python versions prior to 2.7.14 may also be vulnerable and it appears that Python 2.7.17 and prior may also be vulnerable however this has not been confirmed. The vulnerability lies when multiply threads are handling large amounts of data. In both cases there is essentially a race condition that occurs. For the Heap-Buffer-Overflow, Thread 2 is creating the size for a buffer, but Thread1 is already writing to the buffer without knowing how much to write. So when a large amount of data is being processed, it is very easy to cause memory corruption using a Heap-Buffer-Overflow. As for the Use-After-Free, Thread3->Malloc->Thread1->Free's->Thread2-Re-uses-Free'd Memory. The PSRT has stated that this is not a security vulnerability due to the fact that the attacker must be able to run code, however in some situations, such as function as a service, this vulnerability can potentially be used by an attacker to violate a trust boundary, as such the DWF feels this issue deserves a CVE.

CVE-2019-11483 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2020-08-24 2.1 LOW 3.3 LOW
Sander Bos discovered Apport mishandled crash dumps originating from containers. This could be used by a local attacker to generate a crash report for a privileged process that is readable by an unprivileged user.
CVE-2018-16644 3 Canonical, Debian, Imagemagick 3 Ubuntu Linux, Debian Linux, Imagemagick 2020-08-24 4.3 MEDIUM 6.5 MEDIUM
There is a missing check for length in the functions ReadDCMImage of coders/dcm.c and ReadPICTImage of coders/pict.c in ImageMagick 7.0.8-11, which allows remote attackers to cause a denial of service via a crafted image.

CVE-2019-17025 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2020-08-24 6.8 MEDIUM 8.8 HIGH
Mozilla developers reported memory safety bugs present in Firefox 71. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 72.
CVE-2018-18281 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2020-08-24 4.6 MEDIUM 7.8 HIGH
Since Linux kernel version 3.2, the mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. This is fixed in the following kernel versions: 4.9.135, 4.14.78, 4.18.16, 4.19.
CVE-2018-14883 4 Canonical, Debian, Netapp and 1 more 4 Ubuntu Linux, Debian Linux, Storage Automation Store and 1 more 2020-08-24 5.0 MEDIUM 7.5 HIGH
An issue was discovered in PHP before 5.6.37, 7.0.x before 7.0.31, 7.1.x before 7.1.20, and 7.2.x before 7.2.8. An Integer Overflow leads to a heap-based buffer over-read in exif_thumbnail_extract of exif.c.
