gnome-keyring: improper caching of passwords/passphrase

GNOME gnome-keyring 3.4.0 through 3.4.1, when gpg-cache-method is set to "idle" or "timeout," does not properly limit the amount of time a passphrase is cached, which allows attackers to have an unspecified impact via unknown attack vectors.

gnome-screensaver 3.4.x before 3.4.4 and 3.5.x before 3.5.4, when multiple screens are used, only locks the screen with the active focus, which allows physically proximate attackers to bypass screen locking and access an unattended workstation.

The register_application function in atk-adaptor/bridge.c in GNOME at-spi2-atk 2.5.2 does not seed the random number generator and generates predictable temporary file names, which makes it easier for local users to create or truncate files via a symlink attack on a temporary socket file in /tmp/at-spi2.

plug-in): Insecure temporary directory use by loading template files for 'Album', 'Lyrics', and 'Artist' tabs

(1) AlbumTab.py, (2) ArtistTab.py, (3) LinksTab.py, and (4) LyricsTab.py in the Context module in GNOME Rhythmbox 0.13.3 and earlier allows local users to execute arbitrary code via a symlink attack on a temporary HTML template file in the /tmp/context directory.

gdk-pixbuf: DoS (GLib error and application abort) due to an integer overflow in the XBM image file format loader

Multiple integer overflows in the read_bitmap_file_data function in io-xbm.c in gdk-pixbuf before 2.26.1 allow remote attackers to cause a denial of service (application crash) via a negative (1) height or (2) width in an XBM file, which triggers a heap-based buffer overflow.

libsoup: does not indicate whether or not an SSL certificate is valid

libsoup 2.32.2 and earlier does not validate certificates or clear the trust flag when the ssl-ca-file does not exist, which allows remote attackers to bypass authentication by connecting with a SSL connection.

libgdata: Absent validation of SSL certificates

libgdata before 0.10.2 and 0.11.x before 0.11.1 does not validate SSL certificates, which allows remote attackers to obtain user names and passwords via a man-in-the-middle (MITM) attack with a spoofed certificate.

DistUpgrade/DistUpgradeMain.py in Update Manager, as used by Ubuntu 12.04 LTS, 11.10, and 11.04, uses weak permissions for (1) apt-clone_system_state.tar.gz and (2) system_state.tar.gz, which allows local users to obtain repository credentials.

glib2: hash table collisions CPU usage DoS

GLib 2.31.8 and earlier, when the g_str_hash function is used, computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table. NOTE: this issue may be disputed by the vendor; the existence of the g_str_hash function is not a vulnerability in the library, because callers of g_hash_table_new and g_hash_table_new_full can specify an arbitrary hash function that is appropriate for the application.

t1lib: off-by-one errors in token and linetoken

Multiple off-by-one errors in the (1) token and (2) linetoken functions in backend/dvi/mdvi-lib/afmparse.c in t1lib, as used in teTeX 3.0.x, GNOME evince, and possibly other products, allow 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, different vulnerabilities than CVE-2010-2642 and CVE-2011-0433.

Cross-site scripting (XSS) vulnerability in the theme_adium_append_message function in empathy-theme-adium.c in the Adium theme in libempathy-gtk in Empathy 3.2.1 and earlier allows remote attackers to inject arbitrary web script or HTML via a crafted alias (aka nickname) in a /me event, a different vulnerability than CVE-2011-3635.

(1) services/twitter/twitter-contact-view.c and (2) services/twitter/twitter-item-view.c in libsocialweb before 0.25.20 automatically connect to Twitter when no Twitter account is set, which might allow remote attackers to obtain sensitive information via a man-in-the-middle (MITM) attack.

Cross-site scripting (XSS) vulnerability in the theme_adium_append_message function in empathy-theme-adium.c in the Adium theme in libempathy-gtk in Empathy 3.2.1 and earlier allows remote attackers to inject arbitrary web script or HTML via a crafted alias (aka nickname).

NetworkManager: Console user can escalate to root via newlines in ifcfg-rh connection name

Incomplete blacklist vulnerability in the svEscape function in settings/plugins/ifcfg-rh/shvar.c in the ifcfg-rh plug-in for GNOME NetworkManager 0.9.1, 0.9.0, 0.8.1, and possibly other versions, when PolicyKit is configured to allow users to create new connections, allows local users to execute arbitrary commands via a newline character in the name for a new network connection, which is not properly handled when writing to the ifcfg file.

evolution: mailto URL scheme attachment header improper input validation

GNOME Evolution before 3.2.3 allows user-assisted remote attackers to read arbitrary files via the attachment parameter to a mailto: URL, which attaches the file to the email.

qt/harfbuzz buffer overflow

Heap-based buffer overflow in the Lookup_MarkMarkPos function in the HarfBuzz module (harfbuzz-gpos.c), as used by Qt before 4.7.4 and Pango, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted font file.

librsvg: object type mismatch leading to invalid pointer dereference

librsvg before 2.34.1 uses the node name to identify the type of node, which allows context-dependent attackers to cause a denial of service (NULL pointer dereference) and possibly execute arbitrary code via a SVG file with a node with the element name starting with "fe," which is misidentified as a RsvgFilterPrimitive.

libsoup: SoupServer directory traversal flaw

Directory traversal vulnerability in soup-uri.c in SoupServer in libsoup before 2.35.4 allows remote attackers to read arbitrary files via a %2e%2e (encoded dot dot) in a URI.

gdk-pixbuf: incorrect error detection in the GIF image loader

The gdk_pixbuf__gif_image_load function in gdk-pixbuf/io-gif.c in gdk-pixbuf before 2.23.5 does not properly handle certain return values, which allows remote attackers to cause a denial of service (memory consumption) via a crafted GIF image file.

NetworkManager: Did not honour PolicyKit auth_admin action element by creation of Ad-Hoc wireless networks

GNOME NetworkManager before 0.8.6 does not properly enforce the auth_admin element in PolicyKit, which allows local users to bypass intended wireless network sharing restrictions via unspecified vectors.
