NVD Description

Note: Versions mentioned in the description apply only to the upstream glib2-devel package and not the glib2-devel package as distributed by RHEL.

A flaw was found in GLib. A buffer over-read can occur in g_io_channel_read_line_backend() in the giochannel.c file when a custom line terminator with a length greater than one is set, causing memcmp to read past the GString buffer. This vulnerability can cause a minor information disclosure of 7 bytes or a denial of service when the buffer over-read crosses a page boundary.
