Gnome : Security Vulnerabilities, CVEs, Published In August 2012

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.

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 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 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.
