Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Guanxing Wen reports :

PCRE library is prone to a vulnerability which leads to Heap Overflow.
During the compilation of a malformed regular expression, more data is
written on the malloced block than the expected size output by
compile_regex(). The Heap Overflow vulnerability is caused by the
following regular expression.


A dry run of this particular regular expression with pcretest will
reports 'double free or corruption (!prev)'. But it is actually a heap
overflow problem. The overflow only affects pcre 8.x branch, pcre2
branch is not affected.
