AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions Gnome Pango versions 1.42 and later

Description The issue is related to a buffer overflow in the pango log2vis get embedding levels function, specifically with the assignment of nchars and the loop condition. This can be exploited when an application passes invalid UTF-8 strings to functions like pango itemize, potentially allowing a remote attacker to execute arbitrary code.

Recommendations For Gnome Pango versions 1.42 and later, consider disabling the pango log2vis get embedding levels function until a patch is available to prevent potential code execution. Restrict access to functions like pango itemize to minimize the risk of exploitation by invalid UTF-8 strings. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
