Alpine: multiple libpcre16 packages, multiple pcre packages: security update to 8.38-r0 (deprecated)

critical Tenable Self-Hosted Container Security Plugin ID 400978

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- The pcre_compile2 function in pcre_compile.c in PCRE 8.38 mishandles the /((?:F?+(?:^(?(R)a+\"){99}-
))(?J)(?'R'(?'R'<((?'RR'(?'R'\){97)?J)?J)(?'R'(?'R'\){99|(:(?|(?'R')(\k'R')|((?'R')))H'R'R)(H'R))))))/
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. (CVE-2016-1283)

- The compile_branch function in pcre_compile.c in PCRE 8.x before 8.39 and pcre2_compile.c in PCRE2 before
10.22 mishandles patterns containing an (*ACCEPT) substring in conjunction with nested parentheses, which
allows remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer
overflow) via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by
Konqueror, aka ZDI-CAN-3542. (CVE-2016-3191)
