Heap-based buffer overflow in the find_fixedlength function in pcre_compile.c in PCRE before 8.38 allows remote attackers to cause a denial of service (crash) or obtain sensitive information from heap memory and possibly bypass the ASLR protection mechanism via a crafted regular expression with an excess closing parenthesis.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
