The _xrealloc function in xlsp_xmalloc.c in OpenSLP 2.0.0 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a large number of crafted packets, which triggers a memory allocation failure.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The _xrealloc function in xlsp_xmalloc.c in OpenSLP 2.0.0 allows remote attackers to cause a denial of     service (NULL pointer dereference and crash) via a large number of crafted packets, which triggers a     memory allocation failure. (CVE-2016-4912)

Note that Nessus relies on the presence of the package as reported by the vendor.

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

  - Buffer overflow in the SLPFoldWhiteSpace function in     common/slp_compare.c in OpenSLP 2.0 allows remote     attackers to have unspecified impact via a crafted     string.(CVE-2016-7567)

  - The _xrealloc function in xlsp_xmalloc.c in OpenSLP     2.0.0 allows remote attackers to cause a denial of     service (NULL pointer dereference and crash) via a     large number of crafted packets, which triggers a     memory allocation failure.(CVE-2016-4912)

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.

This update for openslp fixes two security issues and two bugs. The following vulnerabilities were fixed :

  - CVE-2016-4912: A remote attacker could have crashed the     server with a large number of packages (bsc#980722)

  - CVE-2016-7567: A remote attacker could cause a memory     corruption having unspecified impact (bsc#1001600) The     following bugfix changes are included :

  - bsc#994989: Removed convenience code as changes bytes in     the message buffer breaking the verification code

  - bsc#974655: Removed no longer needed slpd init file

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