CVE-2023-23301
A malicious CIQ application could craft a string that starts near the end of a section, and whose length extends past its end.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.06%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The `news` MonkeyC operation code in CIQ API version 1.0.0 through 4.1.7 fails to check that string resources are not extending past the end of the expected sections. A malicious CIQ application could craft a string that starts near the end of a section, and whose length extends past its end. Upon loading the string, the GarminOS TVM component may read out-of-bounds memory.
