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

This update was imported from the SUSE:SLE-12:Update update project.

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.

  - openslp: memory corruption due to possible overflow in SLPFoldWhiteSpace in common/slp_compare.c     (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)

  - The Service Location Protocol (SLP, RFC 2608) allows an unauthenticated, remote attacker to register     arbitrary services. This could allow the attacker to use spoofed UDP traffic to conduct a denial-of-     service attack with a significant amplification factor. (CVE-2023-29552)

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 host is affected by the vulnerability described in GLSA-201707-05 (OpenSLP: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in OpenSLP. Please review       the CVE identifiers referenced below for details.
  Impact :

Fix possible overflow in SLPFoldWhiteSpace, CVE-2016-7567

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

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)
