Notes

[wheezy] - pcre3 <not-affected> (Vulnerable code not present)
For wheezy: same code looks present around patched lines, though the
reproducer does not lead to a crash, and just gives
"Matched, but too many substrings"
[squeeze] - pcre3 <not-affected> (Vulnerable code not present)
Fixed in 8.38 upstream
