The read_config_file function in lib/hesiod.c in Hesiod 3.2.1 falls back to the “.athena.mit.edu” default domain when opening the configuration file fails, which allows remote attackers to gain root privileges by poisoning the DNS cache.

The bmp_getdata function in libjasper/bmp/bmp_dec.c in JasPer 1.900.5 allows remote attackers to cause a denial of service (NULL pointer dereference) by calling the imginfo command with a crafted BMP image. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-8690.

The TCP stack in the Linux kernel through 4.10.6 mishandles the SCM_TIMESTAMPING_OPT_STATS feature, which allows local users to obtain sensitive information from the kernel’s internal socket data structures or cause a denial of service (out-of-bounds read) via crafted system calls, related to net/core/skbuff.c and net/socket.c.

Multiple versions of GitLab expose a dangerous method to any authenticated user that could lead to the deletion of all Issue and MergeRequest objects on a GitLab instance. For GitLab instances with publicly available projects this vulnerability could be exploited by an unauthenticated user. A fix was included in versions 8.14.3, 8.13.8, and 8.12.11, which were released on December 5th 2016 at 3:59 PST. The GitLab versions vulnerable to this are 8.13.0, 8.13.0-ee, 8.13.1, 8.13.1-ee, 8.13.2, 8.13.2-ee, 8.13.3, 8.13.3-ee, 8.13.4, 8.13.4-ee, 8.13.5, 8.13.5-ee, 8.13.6, 8.13.6-ee, 8.13.7, 8.14.0, 8.14.0-ee, 8.14.1, 8.14.2, and 8.14.2-ee.

Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are not properly verifying restore privileges when restoring a file. The restore capability of Nextcloud/ownCloud was not verifying whether a user has only read-only access to a share. Thus a user with read-only access was able to restore old versions.

Revive Adserver before 3.2.3 suffers from Cross-Site Request Forgery (CSRF). A number of scripts in Revive Adserver’s user interface are vulnerable to CSRF attacks: `www/admin/banner-acl.php`, `www/admin/banner-activate.php`, `www/admin/banner-advanced.php`, `www/admin/banner-modify.php`, `www/admin/banner-swf.php`, `www/admin/banner-zone.php`, `www/admin/tracker-modify.php`.

An error in the implementation of an autosubscribe feature in the check_stream_exists route of the Zulip group chat application server before 1.4.3 allowed an authenticated user to subscribe to a private stream that should have required an invitation from an existing member to join. The issue affects all previously released versions of the Zulip server.

Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are not properly verifying edit check permissions on WebDAV copy actions. The WebDAV endpoint was not properly checking the permission on a WebDAV COPY action. This allowed an authenticated attacker with access to a read-only share to put new files in there. It was not possible to modify existing files.

Nextcloud Server before 9.0.54 and 10.0.0 suffers from an improper authorization check on removing shares. The Sharing Backend as implemented in Nextcloud does differentiate between shares to users and groups. In case of a received group share, users should be able to unshare the file to themselves but not to the whole group. The previous API implementation simply unshared the file to all users in the group.

Revive Adserver before 3.2.5 and 4.0.0 suffers from Reflected File Download. `www/delivery/asyncspc.php` was vulnerable to the fairly new Reflected File Download (RFD) web attack vector that enables attackers to gain complete control over a victim’s machine by virtually downloading a file from a trusted domain.
