PCRE library is prone to a heap overflow vulnerability. Due to insufficient bounds checking inside compile_branch(), the heap memory could be overflowed via a crafted regular expression. Since PCRE library is widely used, this vulnerability should affect many applications using it. An attacker may exploit this issue to execute arbitrary code in the context of the user running the affected application. (CVE-2015-2325)

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2943-1 advisory.

    It was discovered that PCRE incorrectly handled certain regular expressions. A remote attacker could use     this issue to cause applications using PCRE to crash, resulting in a denial of service, or possibly     execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The SecurityCenter application installed on the remote host is affected by multiple vulnerabilities in the bundled version of PHP that is prior to version 5.4.41. It is, therefore, affected by the following vulnerabilities :

 - A flaw in the phar_parse_tarfile function in     ext/phar/tar.c could allow a denial of service     via a crafted entry in a tar archive.
    (CVE-2015-4021)

  - An integer overflow condition exists in the     ftp_genlist() function in ftp.c due to improper     validation of user-supplied input. A remote attacker can     exploit this to cause a heap-based buffer overflow,     resulting in a denial of service condition or possible     remote code execution. (CVE-2015-4022)

  - Multiple flaws exist related to using pathnames     containing NULL bytes. A remote attacker can exploit     these flaws, by combining the '\0' character with a safe     file extension, to bypass access restrictions. This had     been previously fixed but was reintroduced by a     regression in versions 5.4+. (CVE-2006-7243,     CVE-2015-4025)

  - Multiple heap buffer overflow conditions exist in the     bundled Perl-Compatible Regular Expression (PCRE)     library due to improper validation of user-supplied     input to the compile_branch() and pcre_compile2()     functions. A remote attacker can exploit these     conditions to cause a heap-based buffer overflow,     resulting in a denial of service condition or the     execution of arbitrary code. (CVE-2015-2325,     CVE-2015-2326)

  - A security bypass vulnerability exists due to a flaw in     the pcntl_exec implementation that truncates a pathname     upon encountering the '\x00' character. A remote     attacker can exploit this, via a crafted first argument,     to bypass intended extension restrictions and execute     arbitrary files. (CVE-2015-4026)

  - A flaw exists in the multipart_buffer_headers() function     in rfc1867.c due to improper handling of     multipart/form-data in HTTP requests. A remote attacker     can exploit this flaw to cause a consumption of CPU     resources, resulting in a denial of service condition.
