glibc packages fix security vulnerabilities","description":"The DNS stub resolver in the GNU C Library (aka glibc or libc6) before\nversion 2.26, when EDNS support is enabled, will solicit large UDP\nresponses from name servers, potentially simplifying off-path DNS\nspoofing attacks due to IP fragmentation.(CVE-2017-12132, CVE-2017-12133).\n\nThe GNU C Library (aka glibc or libc6) before 2.27 contains an off-by-one\nerror leading to a heap-based buffer overflow (CVE-2017-15670).\n\nThe glob function in glob.c in the GNU C Library (aka glibc or libc6)\nbefore 2.27, when invoked with GLOB_TILDE, could skip freeing allocated\nmemory when processing the ~ operator with a long user name, potentially\nleading to a denial of service (memory leak) (CVE-2017-15671).\n\nThe glob function in glob.c in the GNU C Library (aka glibc or libc6)\nbefore 2.27 contains a buffer overflow during unescaping of user names\nwith the ~ operator (CVE-2017-15804).\n\nAs libtirpc is also affected by CVE-2017-12133, it's part of this update.\n","status":"published","published":"2017-12-28T13:16:56Z","modified":"2026-04-16T06:25:00.384693342Z","updated_at":"2026-11-02T15:49:40.442238Z"},{"id":"openSUSE-SU-2024:10792-1","title":"glibc-2.34-1.2
