{"id":"USN-3239-1","summary":"eglibc, glibc vulnerabilities","details":"It was discovered that the GNU C Library incorrectly handled the\nstrxfrm() function. An attacker could use this issue to cause a denial\nof service or possibly execute arbitrary code. This issue only affected\nUbuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8982)\n\nIt was discovered that an integer overflow existed in the\n_IO_wstr_overflow() function of the GNU C Library. An attacker could\nuse this to cause a denial of service or possibly execute arbitrary\ncode. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04\nLTS. (CVE-2015-8983)\n\nIt was discovered that the fnmatch() function in the GNU C Library\ndid not properly handle certain malformed patterns. An attacker could\nuse this to cause a denial of service. This issue only affected Ubuntu\n12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8984)\n\nAlexander Cherepanov discovered a stack-based buffer overflow in the\nglob implementation of the GNU C Library. An attacker could use this\nto specially craft a directory layout and cause a denial of service.\n(CVE-2016-1234)\n\nFlorian Weimer discovered a NULL pointer dereference in the DNS\nresolver of the GNU C Library. An attacker could use this to cause\na denial of service. (CVE-2015-5180)\n\nMichael Petlan discovered an unbounded stack allocation in the\ngetaddrinfo() function of the GNU C Library. An attacker could use\nthis to cause a denial of service. (CVE-2016-3706)\n\nAldy Hernandez discovered an unbounded stack allocation in the sunrpc\nimplementation in the GNU C Library. An attacker could use this to\ncause a denial of service. (CVE-2016-4429)\n\nTim Ruehsen discovered that the getaddrinfo() implementation in the\nGNU C Library did not properly track memory allocations. An attacker\ncould use this to cause a denial of service. This issue only affected\nUbuntu 16.04 LTS. (CVE-2016-5417)\n\nAndreas Schwab discovered that the GNU C Library on ARM 32-bit\nplatforms did not properly set up execution contexts. An attacker\ncould use this to cause a denial of service.
