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.

SQL injection vulnerability in users/signup.php in the "signup" component in HamayeshNegar CMS allows a remote attacker to execute arbitrary SQL commands via the "utype" parameter.

kernel: Mishandled extent trees in fs/f2fs/extent_cache.c can allow a local user to cause a denial of service

fs/f2fs/extent_cache.c in the Linux kernel before 4.13 mishandles extent trees, which allows local users to cause a denial of service (BUG) via an application with multiple threads.

smart/calculator/gallerylock/CalculatorActivity.java in the "Photo,Video Locker-Calculator" application through 18 for Android allows attackers to access files via the backdoor 17621762 PIN.

openstack-nova: Swapping encrypted volumes can allow an attacker to corrupt the LUKS header causing a denial of service in the host

An issue was discovered in OpenStack Nova 15.x through 15.1.0 and 16.x through 16.1.1. By detaching and reattaching an encrypted volume, an attacker may access the underlying raw volume and corrupt the LUKS header, resulting in a denial of service attack on the compute host. (The same code error also results in data loss, but that is not a vulnerability because the user loses their own data.) All Nova setups supporting encrypted volumes are affected.

cups: DNS rebinding attacks via incorrect whitelist

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).

sox: NULL pointer dereference in startread function in xa.c

In the startread function in xa.c in Sound eXchange (SoX) through 14.4.2, a corrupt header specifying zero channels triggers an infinite loop with a resultant NULL pointer dereference, which may allow a remote attacker to cause a denial-of-service.

OpenRC opentmpfiles through 0.1.3, when the fs.protected_hardlinks sysctl is turned off, allows local users to obtain ownership of arbitrary files by creating a hard link inside a directory on which "chown -R" will be run.

In ARM mbed TLS before 2.7.0, there is a bounds-check bypass through an integer overflow in PSK identity parsing in the ssl_parse_client_psk_identity() function in library/ssl_srv.c.
