The hb_buffer_ensure function in hb-buffer.c in HarfBuzz, as used in Pango 1.28.3, Firefox, and other products, does not verify that memory reallocations succeed, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) or possibly execute arbitrary code via crafted OpenType font data that triggers use of an incorrect index.Show less

Heap-based buffer overflow in the pango_ft2_font_render_box_glyph function in pango/pangoft2-render.c in libpango in Pango 1.28.3 and earlier, when the FreeType2 backend is enabled, allows user-assisted remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file, related to the glyph box for an FT_Bitmap object.Show less

The (1) tomboy and (2) tomboy-panel scripts in GNOME Tomboy 1.5.2 and earlier place a zero-length directory name in the LD_LIBRARY_PATH, which allows local users to gain privileges via a Trojan horse shared library in the current working directory. NOTE: vector 1 exists because of an incorrect fix for CVE-2005-4790.2.Show less

Epiphany 2.28 and 2.29, when WebKit and LibSoup are used, unconditionally displays a closed-lock icon for any URL beginning with the https: substring, without any warning to the user, which allows man-in-the-middle attackers to spoof arbitrary https web sites via a crafted X.509 server certificate.Show less

gnome-power-manager 2.27.92 does not properly implement the lock_on_suspend and lock_on_hibernate settings for locking the screen when the suspend or hibernate button is pressed, which might make it easier for physically proximate attackers to access an unattended laptop via a resume action, a related issue to CVE-2010-2532. NOTE: this issue exists because of a regression that followed a gnome-power-manager fix a few years earlier.Show less

gnome-power-manager 2.14.0 does not properly implement the lock_on_suspend and lock_on_hibernate settings for locking the screen when the suspend or hibernate button is pressed, which might make it easier for physically proximate attackers to access an unattended laptop via a resume action, a related issue to CVE-2010-2532.Show less

gdk/gdkwindow.c in GTK+ before 2.18.5, as used in gnome-screensaver before 2.28.1, performs implicit paints on windows of type GDK_WINDOW_FOREIGN, which triggers an X error in certain circumstances and consequently allows physically proximate attackers to bypass screen locking and access an unattended workstation by pressing the Enter key many times.Show less

Array index error in the hb_ot_layout_build_glyph_classes function in pango/opentype/hb-ot-layout.cc in Pango before 1.27.1 allows context-dependent attackers to cause a denial of service (application crash) via a crafted font file, related to building a synthetic Glyph Definition (aka GDEF) table by using this font's charmap and the Unicode property database.Show less

gnome-screensaver 2.28.x before 2.28.3 does not properly synchronize the state of screen locking and the unlock dialog in situations involving a change to the number of monitors, which allows physically proximate attackers to bypass screen locking and access an unattended workstation by connecting and disconnecting monitors multiple times, a related issue to CVE-2010-0414.Show less

gnome-screensaver 2.14.3, 2.22.2, 2.27.x, 2.28.0, and 2.28.3, when the X configuration enables the extend screen option, allows physically proximate attackers to bypass screen locking, access an unattended workstation, and view half of the GNOME desktop by attaching an external monitor.Show less

gnome-screensaver 2.26.1 relies on the gnome-session D-Bus interface to determine session idle time, even when an Xfce desktop such as Xubuntu or Mythbuntu is used, which allows physically proximate attackers to access an unattended workstation on which screen locking had been intended.Show less

gnome-screensaver 2.28.0 does not resume adherence to its activation settings after an inhibiting application becomes unavailable on the session bus, which allows physically proximate attackers to access an unattended workstation on which screen locking had been intended.Show less

Buffer overflow in the GMIME_UUENCODE_LEN macro in gmime/gmime-encodings.h in GMime before 2.4.15 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via input data for a uuencode operation.Show less

nm-connection-editor in NetworkManager (NM) 0.7.x exports connection objects over D-Bus upon actions in the connection editor GUI, which allows local users to obtain sensitive information by reading D-Bus signals, as demonstrated by using dbus-monitor to discover the password for the WiFi network.Show less

NetworkManager (NM) 0.7.2 does not ensure that the configured Certification Authority (CA) certificate file for a (1) WPA Enterprise or (2) 802.1x network remains present upon a connection attempt, which might allow remote attackers to obtain sensitive information or cause a denial of service (connectivity disruption) by spoofing the identity of a wireless network.Show less

The FoFiType1::parse function in fofi/FoFiType1.cc in Xpdf 3.0.0, gpdf 2.8.2, kpdf in kdegraphics 3.3.1, and possibly other libraries and versions, does not check the return value of the getNextLine function, which allows context-dependent attackers to execute arbitrary code via a PDF file with a crafted Type 1 font that can produce a negative value, leading to a signed-to-unsigned integer conversion error and a buffer overflow.Show less

The g_file_copy function in glib 2.0 sets the permissions of a target file to the permissions of a symbolic link (777), which allows user-assisted local users to modify files of other users, as demonstrated by using Nautilus to modify the permissions of the user home directory.Show less

GNOME Rhythmbox 0.11.5 allows remote attackers to cause a denial of service (segmentation fault and crash) via a playlist (.pls) file with a long Title field, possibly related to the g_hash_table_lookup function in b-playlist-manager.c.Show less
