BugId: OOBR[0x18]+0{-0x78~0x58#002d} caa.9e4
Location: acrord32.exe!acrord32.dll+0x601BC7
Description: An Access Violation exception happened at 0x39331000 while attempting to read memory at 0x39331000; at the end of a 24/0x18 bytes heap block at 0x39330FE8. This indicates an Out-Of-Bounds (OOB) access bug was triggered. An earlier out-of-bounds write was detected at 0x39330F70, 120/0x78 bytes before that block because it modified the page heap prefix pattern.
Version: AcroRd32.exe: 18.11.20040.19174 (x86)
AcroRd32.dll: 18.11.20040.19174 (x86)
Security impact: Potentially exploitable security issue that might allow information disclosure and (less likely) arbitrary code execution.
