libpcre2-10.23: Fix CVE-2017-7186
A fuzz on libpcre1 through the pcretest utility revealed an invalid read in the
library. For who is interested in a detailed description of the bug, will
follow a feedback from upstream:
This was a genuine bug in the 32-bit library. Thanks for finding it. The crash
was caused by trying to find a Unicode property for a code value greater than
0x10ffff, the Unicode maximum, when running in non-UTF mode (where character
values can be up to 0xffffffff).
The complete ASan output:
# pcretest -32 -d $FILE
==14788==ERROR: AddressSanitizer: SEGV on unknown address 0x7f1bbffed4df (pc 0x7f1bbee3fe6b bp 0x7fff8b50d8c0 sp 0x7fff8b50d3a0 T0)
==14788==The signal is caused by a READ memory access.
