Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Uncontrolled recursion (CVE-ID: CVE-2017-18267)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in the FoFiType1C::cvtGlyph function in fofi/FoFiType1C.cc due to infinite recursion. A remote attacker can trick the victim into opening a specially crafted PDF file and cause the service to crash.
2) Heap-based buffer over-read (CVE-ID: CVE-2018-10733)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in the function ft_font_face_hash of gxps-fonts.c due to heap-based buffer over-read. A remote attacker can trigger memory corruption and cause the service to crash.
3) Stack-based buffer over-read (CVE-ID: CVE-2018-10767)
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.
4) NULL pointer dereference (CVE-ID: CVE-2018-10768)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in the AnnotPath::getCoordsLength function in Annot.h due to NULL pointer dereference. A remote attacker can cause the service to crash.
5) Out-of-bounds read (CVE-ID: CVE-2018-12910)
The vulnerability allows a remote attacker to obtain potentially sensitive information or cause DoS condition on the target system.The weakness exists due to insufficient validation of cookie requests. A remote attacker can supply specially crafted cookie request, trigger out-of-bounds memory read and gain access to arbitrary data or cause the service to crash.
6) Buffer overflow (CVE-ID: CVE-2018-13988)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists in the image rendering functionality due to buffer overflow when handling malicious input. A remote unauthenticated attacker can trick the victim into opening a specially crafted PDF file, trigger memory corruption and cause the system to crash.
