Description
This security bulletin contains information about 3 vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2026-52759)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to uncontrolled resource consumption in MachHeader.parse() when parsing a crafted Mach-O binary. A remote attacker can trick the victim into importing a crafted file to cause a denial of service.
User interaction is required to import the crafted Mach-O file, including through the GUI or headless analysis workflows.
2) Unsafe reflection (CVE-ID: N/A)
CWE-ID: CWE-470 - Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection')
CVSSv4: 8.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary code.
The vulnerability exists due to use of externally-controlled input to select classes or code in ToolOptions.readWrappedOptions() and WrappedCustomOption.readState() when opening a crafted Ghidra project. A remote attacker can trick the victim into opening a malicious project to execute arbitrary code.
User interaction is required to open a crafted Ghidra project, and constructor and static initializer side effects may occur before type casting fails.
3) Out-of-bounds write (CVE-ID: N/A)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: 7.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to execute arbitrary code or cause a denial of service.
The vulnerability exists due to out-of-bounds write in the udiv128 simplification helper when processing a loaded binary that contains a compiler-emitted divide-by-constant pattern during decompilation. A remote user can provide a specially crafted binary to execute arbitrary code or cause a denial of service.
The issue is reachable from the RuleDivOpt simplification rule in the Ghidra C++ decompiler, and successful exploitation depends on stack layout and stack-protector configuration.
