Description Agostino Sarubbo gentoo-dev 2016-01-03 09:48:58 UTC
From ${URL} :

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. Carefully crafted my lead to code execution in the context
of affected applications.


@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

CVE-2016-1283 (
  The pcre_compile2 function in pcre_compile.c in PCRE 8.38 mishandles the
  pattern and related patterns with named subgroups, which allows remote
  attackers to cause a denial of service (heap-based buffer overflow) or
  possibly have unspecified other impact via a crafted regular expression, as
  demonstrated by a JavaScript RegExp object encountered by Konqueror.
