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 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.

  - glibc: Incorrect handling of RPATH in elf/dl-load.c can be used to execute code loaded from arbitrary     libraries (CVE-2017-16997)

  - glibc: regular-expression match via proceed_next_node in posix/regexec.c leads to heap-based buffer over-     read (CVE-2019-9169)

  - The posix_spawn_file_actions_addopen function in glibc before 2.20 does not copy its path argument in     accordance with the POSIX specification, which allows context-dependent attackers to trigger use-after-     free vulnerabilities. (CVE-2014-4043)

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 Redhat Enterprise Linux 6 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.

  - glibc: Incorrect handling of RPATH in elf/dl-load.c can be used to execute code loaded from arbitrary     libraries (CVE-2017-16997)

  - glibc: regular-expression match via proceed_next_node in posix/regexec.c leads to heap-based buffer over-     read (CVE-2019-9169)

  - In the GNU C Library (aka glibc or libc6) before 2.28, parse_reg_exp in posix/regcomp.c misparses     alternatives, which allows attackers to cause a denial of service (assertion failure and application exit)     or trigger an incorrect result by attempting a regular-expression match. (CVE-2009-5155)

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 Redhat Enterprise Linux 5 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.

  - glibc: Incorrect handling of RPATH in elf/dl-load.c can be used to execute code loaded from arbitrary     libraries (CVE-2017-16997)

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.
