Hi, the following vulnerability was published for pcre3. CVE-2017-7186[0]: | libpcre1 in PCRE 8.40 and libpcre2 in PCRE2 10.23 allow remote | attackers to cause a denial of service (segmentation violation for read | access, and application crash) by triggering an invalid Unicode | property lookup. The bug is in the 32-bit library. Quoting 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 bug was in both PCRE1 and PCRE2. I have fixed both of them. I have not yet checked if pcre2 in the version in unstable is as well affected, but I guess so and will open a separate bug for it. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

Older version yet unchecked.
