GTK+ 3.10.9 and earlier, as used in cinnamon-screensaver, gnome-screensaver, and other applications, allows physically proximate attackers to bypass the lock screen by pressing the menu button.
Directory traversal vulnerability in the gcab_folder_extract function in libgcab/gcab-folder.c in gcab 0.4 allows remote attackers to write to arbitrary files via crafted path in a CAB file, as demonstrated by "\tmp\moo."
GNOME Shell 3.14.x before 3.14.1, when the Screen Lock feature is used, does not limit the aggregate memory consumption of all active PrtSc requests, which allows physically proximate attackers to execute arbitrary commands on an unattended workstation by making many PrtSc requests and leveraging a temporary lock outage, and the resulting temporary shell availability, caused by the Linux kernel OOM killer.
The "insert-blank-characters" capability in caps.c in gnome-terminal (vte) before 0.28.1 allows remote authenticated users to cause a denial of service (CPU and memory consumption and crash) via a crafted file, as demonstrated by a file containing the string "\033[100000000000000000@".
GNOME Display Manager (gdm) 3.4.1 and earlier, when disable-user-list is set to true, allows local users to cause a denial of service (unable to login) by pressing the cancel button after entering a user name.
The automatic screen lock functionality in GNOME Shell (aka gnome-shell) before 3.10 does not prevent access to the "Enter a Command" dialog, which allows physically proximate attackers to execute arbitrary commands by leveraging an unattended workstation.
js/ui/screenShield.js in GNOME Shell (aka gnome-shell) before 3.8 allows physically proximate attackers to execute arbitrary commands by leveraging an unattended workstation with the keyboard focus on the Activities search.
Heap-based buffer overflow in the ms_escher_get_data function in plugins/excel/ms-escher.c in GNOME Office Gnumeric before 1.12.9 allows remote attackers to cause a denial of service (crash) via a crafted xls file with a crafted length value.
Integer overflow in the load_image function in file-xwd.c in the X Window Dump (XWD) plug-in in GIMP 2.6.9 and earlier, when used with glib before 2.24, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large color entries value in an X Window System (XWD) image dump.
Heap-based buffer overflow in the read_xwd_cols function in file-xwd.c in the X Window Dump (XWD) plug-in in GIMP 2.6.9 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an X Window System (XWD) image dump with more colors than color map entries.
