Name of the Vulnerable Software and Affected Versions GLib (affected versions not specified)
Description An off-by-one error exists in the gvs tuple is normal() function within the glib/gvariant-serialiser.c file. The issue occurs during an alignment padding check where the bounds check incorrectly uses the > operator instead of >=, leading to an out-of-bounds read of a single byte. This can result in a minor information disclosure of one byte or a denial of service if the read operation crosses a page boundary.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
