libgda is the library handling the data abstraction layer in the Gnome data access architecture (GNOME-DB). It can also be used by non-GNOME applications to manage data stored in databases or XML files.
Steve Kemp discovered two format string vulnerabilities in the gda_log_error and gda_log_message functions. Some applications may pass untrusted input to those functions and be vulnerable.
An attacker could pass malicious input to an application making use of the vulnerable libgda functions, potentially resulting in the execution of arbitrary code with the rights of that application.
There is no known workaround at this time.
All libgda users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=gnome-extra/libgda-1.2.2-r1"
