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.
