The xdr_bytes and xdr_string functions in the GNU C Library (aka glibc or libc6) 2.25 mishandle failures of buffer deserialization, which allows remote attackers to cause a denial of service (virtual memory allocation, or memory consumption if an overcommit setting is not used) via a crafted UDP packet to port 111, a related issue to CVE-2017-8779. NOTE: [Information provided from upstream and references

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

  - The xdr_bytes and xdr_string functions in the GNU C Library (aka glibc or libc6) 2.25 mishandle failures     of buffer deserialization, which allows remote attackers to cause a denial of service (virtual memory     allocation, or memory consumption if an overcommit setting is not used) via a crafted UDP packet to port     111, a related issue to CVE-2017-8779. NOTE: [Information provided from upstream and references     (CVE-2017-8804)

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

This update for glibc fixes the following issues: Security issues :

  - CVE-2017-8804: Fix memory leak after deserialization     failure in xdr_bytes, xdr_string (bsc#1037930)

  - CVE-2017-12132: Reduce EDNS payload size to 1200 bytes     (bsc#1051791)

  - CVE-2018-6485,CVE-2018-6551: Fix integer overflows in     internal memalign and malloc functions (bsc#1079036)

  - CVE-2018-1000001: Avoid underflow of malloced area in     realpath (bsc#1074293) Also a non security issue was     fixed :

  - Do not fail if one of the two responses to AF_UNSPEC     fails (bsc#978209)

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.
