Hi,
the following vulnerability was published for glibc, opening the bug
to track the issue as well in the BTS.
CVE-2017-8804[0]:
| 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.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
