In PCRE 8.41, the OP_KETRMAX feature in the match function in pcre_exec.c allows stack exhaustion (uncontrolled recursion) when processing a crafted regular expression.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - pcre: Integer overflow caused by missing check for certain conditions (8.38/31) (CVE-2015-8394)

  - PCRE before 8.36 mishandles the /(((a\2)|(a*)\g<-1>))*/ pattern and related patterns with certain internal     recursive back references, which allows remote attackers to cause a denial of service (segmentation fault)     or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a     JavaScript RegExp object encountered by Konqueror. (CVE-2015-2327)

  - PCRE 7.8 and 8.32 through 8.37, and PCRE2 10.10 mishandle group empty matches, which might allow remote     attackers to cause a denial of service (stack-based buffer overflow) via a crafted regular expression, as     demonstrated by /^(?:(?(1)\\.|([^\\\\W_])?)+)+$/. (CVE-2015-3217)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - pcre: Integer overflow caused by missing check for certain conditions (8.38/31) (CVE-2015-8394)

  - The match function in pcre_exec.c in PCRE before 8.37 mishandles the     /(?:((abcd))|(((?:(?:(?:(?:abc|(?:abcdef))))b)abcdefghi)abc)|((*ACCEPT)))/ pattern and related patterns     involving (*ACCEPT), which allows remote attackers to obtain sensitive information from process memory or     cause a denial of service (partially initialized memory and application crash) via a crafted regular     expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror, aka ZDI-CAN-2547.
    (CVE-2015-8382)

  - PCRE before 8.38 mishandles the interaction of lookbehind assertions and mutually recursive subpatterns,     which allows remote attackers to cause a denial of service (buffer overflow) or possibly have unspecified     other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered     by Konqueror. (CVE-2015-8386)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - pcre: inefficient posix character class syntax check (8.38/16) (CVE-2015-8391)

  - pcre: Integer overflow caused by missing check for certain conditions (8.38/31) (CVE-2015-8394)

  - PCRE before 8.36 mishandles the /(((a\2)|(a*)\g<-1>))*/ pattern and related patterns with certain internal     recursive back references, which allows remote attackers to cause a denial of service (segmentation fault)     or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a     JavaScript RegExp object encountered by Konqueror. (CVE-2015-2327)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
