Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2016-9082)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to integer overflow in the write_png function. A remote attacker can send a specially crafted large svg file, trigger invalid pointer dereference and cause the service to crash.
2) Out-of-bounds read (CVE-ID: CVE-2017-9814)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in cairo-truetype-subset.c due to out-of-bounds read because of mishandling of an unexpected malloc(0) call. A remote attacker can cause the service to crash.
3) Infinite loop (CVE-ID: CVE-2019-6462)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in the function _arc_error_normalized in the file cairo-arc.c, related to _arc_max_angle_for_tolerance_normalized. A remote attacker can consume all available system resources and cause denial of service conditions.
4) Stack-based buffer overflow (CVE-ID: CVE-2020-35492)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
A flaw was found in cairo's image-compositor.c in all versions prior to 1.17.4. This flaw allows an attacker who can provide a crafted input file to cairo's image-compositor (for example, by convincing a user to open a file in an application using cairo, or if an application uses cairo on untrusted input) to cause a stack buffer overflow -> out-of-bounds WRITE. The highest impact from this vulnerability is to confidentiality, integrity, as well as system availability.
