CVE-2018-10767 – libgxps: Stack-based buffer overflow in calling glib in gxps_images_guess_content_type of gcontenttype.c

https://notcve.org/view.php?id=CVE-2018-10767

There is a stack-based buffer over-read in calling GLib in the function gxps_images_guess_content_type of gxps-images.c in libgxps through 0.3.0 because it does not reject negative return values from a g_input_stream_read call. A crafted input will lead to a remote denial of service attack. Hay una sobrelectura de búfer basada en pila en la llamada a GLib en la función gxps_images_guess_content_type de gxps-images.c en libgxps hasta la versión 0.3.0 debido a que no rechaza los valores de retorno de una llamada g_input_stream_read. Se podría realizar un ataque de denegación de servicio remoto con una entrada especialmente manipulada. • https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3140 https://access.redhat.com/errata/RHSA-2018:3505 https://bugzilla.redhat.com/show_bug.cgi?id=1575188 https://access.redhat.com/security/cve/CVE-2018-10767 https://bugzilla.redhat.com/show_bug.cgi?id=1576175 • CWE-121: Stack-based Buffer Overflow CWE-125: Out-of-bounds Read •
