Categoría:	Mageia Linux Local Security Checks
Título:	Mageia: Security Advisory (MGASA-2017-0464)
Resumen:	The remote host is missing an update for the 'glibc, libtirpc' package(s) announced via the MGASA-2017-0464 advisory.
Descripción:	Summary: The remote host is missing an update for the 'glibc, libtirpc' package(s) announced via the MGASA-2017-0464 advisory. Vulnerability Insight: The DNS stub resolver in the GNU C Library (aka glibc or libc6) before version 2.26, when EDNS support is enabled, will solicit large UDP responses from name servers, potentially simplifying off-path DNS spoofing attacks due to IP fragmentation.(CVE-2017-12132, CVE-2017-12133). The GNU C Library (aka glibc or libc6) before 2.27 contains an off-by-one error leading to a heap-based buffer overflow (CVE-2017-15670). The glob function in glob.c in the GNU C Library (aka glibc or libc6) before 2.27, when invoked with GLOB_TILDE, could skip freeing allocated memory when processing the ~ operator with a long user name, potentially leading to a denial of service (memory leak) (CVE-2017-15671). The glob function in glob.c in the GNU C Library (aka glibc or libc6) before 2.27 contains a buffer overflow during unescaping of user names with the ~ operator (CVE-2017-15804). As libtirpc is also affected by CVE-2017-12133, it's part of this update. Affected Software/OS: 'glibc, libtirpc' package(s) on Mageia 6. Solution: Please install the updated package(s). CVSS Score: 7.5 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
