nodejs-moment: Regular expression denial of service

The moment module before 2.19.3 for Node.js is prone to a regular expression denial of service via a crafted date string, a different vulnerability than CVE-2016-4055.

In Exponent CMS before 2.4.1 Patch #6, certain admin users can elevate their privileges.

An issue was discovered in JerryScript 1.0. There is a heap-based buffer over-read in the lit_read_code_unit_from_hex function in lit/lit-char-helpers.c via a RegExp("[\x0"); payload.

ImageMagick: NULL pointer dereference in saveBinaryCLProgram in magick/opencl.c

In ImageMagick 7.0.7, a NULL pointer dereference vulnerability was found in the function saveBinaryCLProgram in magick/opencl.c because a program-lookup result is not checked, related to CacheOpenCLKernel.

ImageMagick: NULL pointer dereference in BenchmarkOpenCLDevices in MagickCore/opencl.c

In ImageMagick 7.0.7, a NULL pointer dereference vulnerability was found in the function BenchmarkOpenCLDevices in MagickCore/opencl.c because a memory allocation result is not checked.

ImageMagick: NULL pointer dereference in GetOpenCLCachedFilesDirectory function in magick/opencl.c

In the GetOpenCLCachedFilesDirectory function in magick/opencl.c in ImageMagick 7.0.7, a NULL pointer dereference vulnerability occurs because a memory allocation result is not checked, related to GetOpenCLCacheDirectory.

kernel: Inifinite loop vulnerability in mm/madvise.c:madvise_willneed() function allows local denial of service

The madvise_willneed function in mm/madvise.c in the Linux kernel before 4.14.4 allows local users to cause a denial of service (infinite loop) by triggering use of MADVISE_WILLNEED for a DAX mapping.

The Wave_read._read_fmt_chunk function in Lib/wave.py in Python through 3.6.4 does not ensure a nonzero channel value, which allows attackers to cause a denial of service (divide-by-zero and exception) via a crafted wav format audio file. NOTE: the vendor disputes this issue because Python applications "need to be prepared to handle a wide variety of exceptions.

zsh: buffer overrun in symlinks

In utils.c in zsh before 5.4, symlink expansion had a buffer overflow.

zsh: NULL dereference in cd in sh compatibility mode under given circumstances

In builtin.c in zsh before 5.4, when sh compatibility mode is used, there is a NULL pointer dereference during processing of the cd command with no argument if HOME is not set.

kernel: Deadlock caused in fs/ocfs2/file.c:ocfs2_setattr() can allow local users to cause a denial of service

The ocfs2_setattr function in fs/ocfs2/file.c in the Linux kernel before 4.14.2 allows local users to cause a denial of service (deadlock) via DIO requests.

kernel: Race condition in drivers/md/dm.c:dm_get_from_kobject() allows local users to cause a denial of service

The dm_get_from_kobject function in drivers/md/dm.c in the Linux kernel before 4.14.3 allow local users to cause a denial of service (BUG) by leveraging a race condition with __dm_destroy during creation and removal of DM devices.

kernel: Infoleak/use-after-free in __oom_reap_task_mm function in mm/oom_kill.c

The __oom_reap_task_mm function in mm/oom_kill.c in the Linux kernel before 4.14.4 mishandles gather operations, which allows attackers to cause a denial of service (TLB entry leak or use-after-free) or possibly have unspecified other impact by triggering a copy_to_user call within a certain time window.

libcdio: Double free in get_cdtext_generic() in lib/driver/_cdio_generic.c

An issue was discovered in GNU libcdio before 2.0.0. There is a double free in get_cdtext_generic() in lib/driver/_cdio_generic.c.

kernel: mishandling reference counts associated with f2fs_wait_discard_bios calls allowing local attacker to cause denial of service

The f2fs implementation in the Linux kernel before 4.14 mishandles reference counts associated with f2fs_wait_discard_bios calls, which allows local users to cause a denial of service (BUG), as demonstrated by fstrim.

libcdio: NULL pointer dereference in realloc_symlink in rock.c

realloc_symlink in rock.c in GNU libcdio before 1.0.0 allows remote attackers to cause a denial of service (NULL Pointer Dereference) via a crafted iso file.

libcdio: Heap-based buffer over-read in print_iso9660_recurse function in iso-info.c

print_iso9660_recurse in iso-info.c in GNU libcdio before 1.0.0 allows remote attackers to cause a denial of service (heap-based buffer over-read) or possibly have unspecified other impact via a crafted iso file.

jgraphx: XML External Entity (XXE) vulnerability in mxGraphViewImageReader.java:convert()

In mxGraphViewImageReader.java in mxGraph before 3.7.6, the SAXParserFactory instance in convert() is missing flags to prevent XML External Entity (XXE) attacks, as demonstrated by /ServerView.

Leptonica 1.74.4 constructs unintended pathnames (containing duplicated path components) when operating on files in /tmp subdirectories, which might allow local users to bypass intended file restrictions by leveraging access to a directory located deeper within the /tmp directory tree, as demonstrated by /tmp/ANY/PATH/ANY/PATH/input.tif.

An issue was discovered in tools/conversations/view_ajax.php in Concrete5 before 8.3.0. An unauthenticated user can enumerate comments from all blog posts by POSTing requests to /index.php/tools/required/conversations/view_ajax with incremental 'cnvID' integers.
