memcached version prior to 1.4.37 contains an Integer Overflow vulnerability in items.c:item_free() that can result in data corruption and deadlocks due to items existing in hash table being reused from free list. This attack appear to be exploitable via network connectivity to the memcached service. This vulnerability appears to have been fixed in 1.4.37 and later.

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.

  - memcached: Integer Overflow in items.c:item_free() (CVE-2018-1000127)

  - The try_read_command function in memcached.c in memcached before 1.4.39 allows remote attackers to cause a     denial of service (segmentation fault) via a request to add/set a key, which makes a comparison between     signed and unsigned int and triggers a heap-based buffer over-read. NOTE: this vulnerability exists     because of an incomplete fix for CVE-2016-8705. (CVE-2017-9951)

  - Memcached version 1.5.5 contains an Insufficient Control of Network Message Volume (Network Amplification,     CWE-406) vulnerability in the UDP support of the memcached server that can result in denial of service via     network flood (traffic amplification of 1:50,000 has been reported by reliable sources). This attack     appear to be exploitable via network connectivity to port 11211 UDP. This vulnerability appears to have     been fixed in 1.5.6 due to the disabling of the UDP protocol by default. (CVE-2018-1000115)

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 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.

  - memcached: Integer Overflow in items.c:item_free() (CVE-2018-1000127)

  - Multiple integer signedness errors in the (1) process_bin_sasl_auth, (2) process_bin_complete_sasl_auth,     (3) process_bin_update, and (4) process_bin_append_prepend functions in Memcached 1.4.5 and earlier allow     remote attackers to cause a denial of service (crash) via a large body length value in a packet.
    (CVE-2011-4971)

  - The process_bin_delete function in memcached.c in memcached 1.4.4 and other versions before 1.4.17, when     running in verbose mode, allows remote attackers to cause a denial of service (segmentation fault) via a     request to delete a key, which does not account for the lack of a null terminator in the key and triggers     a buffer over-read when printing to stderr. (CVE-2013-0179)

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

According to the versions of the memcached package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - memcached before 1.4.17, when running in verbose mode,     allows remote attackers to cause a denial of service     (crash) via a request that triggers an 'unbounded key     print' during logging, related to an issue that was     'quickly grepped out of the source tree,' a different     vulnerability than CVE-2013-0179 and     CVE-2013-7290.(CVE-2013-7291)

  - An integer overflow flaw, leading to a heap-based     buffer overflow, was found in memcached's parsing of     SASL authentication messages. An attacker could create     a specially crafted message that would cause the     memcached server to crash or, potentially, execute     arbitrary code.(CVE-2016-8706)

  - An integer overflow flaw, leading to a heap-based     buffer overflow, was found in the memcached binary     protocol. An attacker could create a specially crafted     message that would cause the memcached server to crash     or, potentially, execute arbitrary code.(CVE-2016-8704)

  - The process_bin_delete function in memcached.c in     memcached 1.4.4 and other versions before 1.4.17, when     running in verbose mode, allows remote attackers to     cause a denial of service (segmentation fault) via a     request to delete a key, which does not account for the     lack of a null terminator in the key and triggers a     buffer over-read when printing to     stderr.(CVE-2013-0179)

  - The do_item_get function in items.c in memcached 1.4.4     and other versions before 1.4.17, when running in     verbose mode, allows remote attackers to cause a denial     of service (segmentation fault) via a request to delete     a key, which does not account for the lack of a null     terminator in the key and triggers a buffer over-read     when printing to stderr, a different vulnerability than     CVE-2013-0179.(CVE-2013-7290)

Several vulnerabilities were discovered in memcached, a high-performance memory object caching system. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2017-9951     Daniel Shapira reported a heap-based buffer over-read in     memcached (resulting from an incomplete fix for     CVE-2016-8705 ) triggered by specially crafted requests     to add/set a key and allowing a remote attacker to cause     a denial of service.

  - CVE-2018-1000115     It was reported that memcached listens to UDP by     default. A remote attacker can take advantage of it to     use the memcached service as a DDoS amplifier.

  Default installations of memcached in Debian are not affected by   this issue as the installation defaults to listen only on localhost.
  This update disables the UDP port by default. Listening on the UDP   can be re-enabled in the /etc/memcached.conf (cf.
  /usr/share/doc/memcached/NEWS.Debian.gz).

  - CVE-2018-1000127     An integer overflow was reported in memcached, resulting     in resource leaks, data corruption, deadlocks or     crashes.

According to the version of the memcached package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - In SQLite through 3.22.0, databases whose schema is     corrupted using a CREATE TABLE AS statement could cause     a NULL pointer dereference, related to build.c and     prepare.c.(CVE-2018-8740)

memcached version prior to 1.4.37 contains an Integer Overflow vulnerability that can result in data corruption and deadlocks. This attack is exploitable via network connectivity to the memcached service.

For Debian 7 'Wheezy', these problems have been fixed in version 1.4.13-0.2+deb7u4.

We recommend that you upgrade your memcached packages.
