NVD Description

Note: Versions mentioned in the description apply only to the upstream gstreamer1-plugins-ugly-free package and not the gstreamer1-plugins-ugly-free package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

A flaw was found in GStreamer's RealMedia demuxer in the gst-plugins-ugly package. When processing a RealMedia file containing a specially crafted FILEINFO metadata section, the demuxer parses variable-name and variable-value pairs using re_skip_pascal_string() without validating that offsets remain within the mapped buffer. Additionally, the element count controlling the parsing loop is read from attacker-controlled data without validation, which can cause an infinite loop. A crafted RealMedia file can cause the application to crash, hang, or potentially read limited adjacent memory contents.
