-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)
