NetworkManager: Password to unlock the certificate is being logged

The destroy_one_secret function in nm-setting-vpn.c in libnm-util in the NetworkManager package 0.8.999-3.git20110526 in Fedora 15 creates a log entry containing a certificate password, which allows local users to obtain sensitive information by reading a log file.

gdm: URI scheme handling change in glib2 allows running default browser in GDM session

GNOME Display Manager (gdm) before 2.32.2, when glib 2.28 is used, enables execution of a web browser with the uid of the gdm account, which allows local users to gain privileges via vectors involving the x-scheme-handler/http MIME type.

gdm: privilege escalation vulnerability

GNOME Display Manager (gdm) 2.x before 2.32.1 allows local users to change the ownership of arbitrary files via a symlink attack on a (1) dmrc or (2) face icon file under /var/cache/gdm/.

t1lib: Heap-based buffer overflow DVI file AFM font parser

Heap-based buffer overflow in the linetoken function in afmparse.c in t1lib, as used in teTeX 3.0.x, GNOME evince, and possibly other products, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a DVI file containing a crafted Adobe Font Metrics (AFM) file, a different vulnerability than CVE-2010-2642.

pango: missing memory reallocation failure checking in hb_buffer_ensure

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.

pango: Heap-based buffer overflow by rendering glyph box for certain FT_Bitmap objects

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.

Untrusted search path vulnerability in modules/engines/ms-windows/xp_theme.c in GTK+ before 2.24.0 allows local users to gain privileges via a Trojan horse uxtheme.dll file in the current working directory, a different vulnerability than CVE-2010-4831.

Untrusted search path vulnerability in gdk/win32/gdkinput-win32.c in GTK+ before 2.21.8 allows local users to gain privileges via a Trojan horse Wintab32.dll file in the current working directory.

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.

gnome-shell in GNOME Shell 2.31.5 places 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.

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.

vte: responds to get window title escape sequence request

The vte_sequence_handler_window_manipulation function in vteseq.c in libvte (aka libvte9) in VTE 0.25.1 and earlier, as used in gnome-terminal, does not properly handle escape sequences, which allows remote attackers to execute arbitrary commands or obtain potentially sensitive information via a (1) window title or (2) icon title sequence. NOTE: this issue exists because of a CVE-2003-0070 regression.

gdm: logs user passwors that contain invalid UTF8-encoded characters, in debug mode

vicious-extensions/ve-misc.c in GNOME Display Manager (gdm) 2.20.x before 2.20.11, when GDM debug is enabled, logs the user password when it contains invalid UTF8 encoded characters, which might allow local users to gain privileges by reading the information from syslog logs.

gnome-screensaver: Race condition between shaking the unlock dialog and clearing the screen

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.

gnome-screensaver: loses its unlock dialog and keyboard grab sometimes when plugging and unplugging monitor repeatedly

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.

libpangoft2 segfaults on forged font files

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.

gnome-screensaver: loses its unlock dialog and keyboard grab sometimes when unplugging monitor

gnome-screensaver before 2.28.2 allows physically proximate attackers to bypass screen locking and access an unattended workstation by moving the mouse position to an external monitor and then disconnecting that monitor.

gmime22: Buffer overflow by calculating the maximum number of output bytes generated by an uuencode operation

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.

gnome-screensaver insecurely unlocks screen when moving from one monitor to two

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.

gnome-power-manager: Screen not locked on resume from hibernate / suspend

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.
