CVE-2023-51106 [HIGH] MuPDF vulnerabilities
Title: MuPDF vulnerabilities
Summary: Several security issues were fixed in MuPDF.
It was discovered that MuPDF could be made to divide by zero. An attacker
could possibly use this issue to cause a denial of service.
(CVE-2023-51103, CVE-2023-51104, CVE-2023-51105, CVE-2023-51106)
It was discovered that MuPDF incorrectly handled memory under certain
circumstances, which could lead to a NULL pointer dereference. An
attacker could potentially use this issue to cause a denial of service.
(CVE-2024-46657)
It was discovered that MuPDF could enter an infinite recursion when
parsing certain PDF files. An attacker could possibly use this issue to
cause a denial of service. (CVE-2025-46206)
Instructions: In general, a standard system update will make all the necessary changes.
