high Nessus Plugin ID 110743

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the pcre packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - The pcre_exec function in pcre_exec.c in PCRE before 8.38 mishandles a // pattern with a \\01 string, 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-2015-8380)

 - PCRE before 8.38 mishandles (?123) subroutine calls and related subroutine calls, which allows remote attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.(CVE-2015-8387)

 - PCRE before 8.38 mishandles the [: and \\\\ substrings in character classes, which allows remote attackers to cause a denial of service (uninitialized memory read) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.(CVE-2015-8390)

 - PCRE before 8.38 mishandles the (?(digits) and (?(R digits) conditions, which allows remote attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.(CVE-2015-8394)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution
