From: Bernd Kuhls Date: Thu, 13 Jul 2017 19:39:28 +0000 (+0200) Subject: package/pcre: security bump to version 8.41 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bc6a84bb3d05e0d752ecf59bb35ac827e9b76185;p=buildroot.git package/pcre: security bump to version 8.41 Removed patches 0003 & 0004, applied upstream. Fixes the following security issues: CVE-2017-7244 - The _pcre32_xclass function in pcre_xclass.c in libpcre1 in PCRE 8.40 allows remote attackers to cause a denial of service (invalid memory read) via a crafted file. CVE-2017-7245 - Stack-based buffer overflow in the pcre32_copy_substring function in pcre_get.c in libpcre1 in PCRE 8.40 allows remote attackers to cause a denial of service (WRITE of size 4) or possibly have unspecified other impact via a crafted file. CVE-2017-7246 - Stack-based buffer overflow in the pcre32_copy_substring function in pcre_get.c in libpcre1 in PCRE 8.40 allows remote attackers to cause a denial of service (WRITE of size 268) or possibly have unspecified other impact via a crafted file.
