Chris Coulson reported gnome-screensaver is prone to race condition between two subsequent actions -- shaking the unlock dialog and clearing the screen. A local attacker could use this flaw to cause a denial of service (gnome-screensaver crash), which allows physically proximate attackers to access an unattended workstation on which screen locking had been intended.

The GdkPixbufLoader function in GIMP ToolKit (GTK+) in GTK 2 (gtk2) before 2.4.13 allows context-dependent attackers to cause a denial of service (crash) via a malformed image file.
Integer overflow in io-xpm.c in gdk-pixbuf 0.22.0 in GTK+ before 2.8.7 allows attackers to cause a denial of service (crash) or execute arbitrary code via an XPM file with large height, width, and colour values, a different vulnerability than CVE-2005-3186.
io-xpm.c in the gdk-pixbuf XPM image rendering library in GTK+ before 2.8.7 allows attackers to cause a denial of service (infinite loop) via a crafted XPM image with a large number of colors.
Double free vulnerability in gtk 2 (gtk2) before 2.2.4 allows remote attackers to cause a denial of service (crash) via a crafted BMP image.
Directory traversal vulnerability in gftp before 2.0.18 for GTK+ allows remote malicious FTP servers to read arbitrary files via .. (dot dot) sequences in filenames returned from a LIST command.
Integer overflow in the ICO image decoder for (1) gdk-pixbuf before 0.22 and (2) gtk2 before 2.2.4 allows remote attackers to cause a denial of service (application crash) via a crafted ICO file.
The BMP image processor for (1) gdk-pixbuf before 0.22 and (2) gtk2 before 2.2.4 allows remote attackers to cause a denial of service (infinite loop) via a crafted BMP file.
Stack-based buffer overflow in xpmextractcolor (io-xpm.c) in the XPM image decoder for gtk+ 2.4.4 (gtk2) and earlier, and gdk-pixbuf before 0.22, may allow remote attackers to execute arbitrary code via a certain color string. NOTE: this identifier is ONLY for gtk+. It was incorrectly referenced in an advisory for a different issue (CVE-2004-0688).
Integer overflow in pixbufcreatefromxpm (io-xpm.c) in the XPM image decoder for gtk+ 2.4.4 (gtk2) and earlier, and gdk-pixbuf before 0.22, allows remote attackers to execute arbitrary code via certain ncol and cpp values that enable a heap-based buffer overflow. NOTE: this identifier is ONLY for gtk+. It was incorrectly referenced in an advisory for a different issue (CVE-2004-0687).
GTK+ library allows local users to specify arbitrary modules via the GTKMODULES environmental variable, which could allow local users to gain privileges if GTK+ is used by a setuid/setgid program.
