Description
This security bulletin contains information about 1 vulnerability.
1) Stack-based buffer over-read (CVE-ID: CVE-2018-10767)
CWE-ID: CWE-126 - Buffer over-read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.
The weakness exists in the gxps_images_guess_content_type function due to improper rejection of negative return values from a g_input_stream_read call. A remote attacker can submit a specially crafted request, trigger stack-based buffer overread when calling GLib in the gxps_images_guess_content_typefunction, as defined in the gxps-images.c source code file, and cause the service to crash.
