A local attacker who\ncan control the input buffer and size passed to getcwd() in a setuid program\ncould use this flaw to potentially execute arbitrary code and escalate their\nprivileges on the system (CVE-2021-3999).\n\nOther upstream fixes in this update:\n- gconv: Do not emit spurious NUL character in ISO-2022-JP-3 [BZ #28524]\n- x86: Fix __wcsncmp_avx2 in strcmp-avx2.S [BZ #28755]\n- x86: Set Prefer_No_VZEROUPPER and add Prefer_AVX2_STRCMP\n- x86-64: Add ifunc-avx2.h functions with 256-bit EVEX\n- x86-64: Add strcpy family functions with 256-bit EVEX\n- x86-64: Add memmove family functions with 256-bit EVEX\n- x86-64: Add memset family functions with 256-bit EVEX\n- x86-64: Add memcmp family functions with 256-bit EVEX\n- x86-64: Add AVX optimized string/memory functions for RTM\n- x86: Add string/memory function tests in RTM region\n- x86-64: Use ZMM16-ZMM31 in AVX512 memset family functions\n- x86-64: Use ZMM16-ZMM31 in AVX512 memmove family functions\n- test-strnlen.c: Initialize wchar_t string with wmemset [BZ #27655]\n- test-strnlen.c: Check that strnlen won't go beyond the maximum length\n- x86: Optimize memchr-avx2.S\n- x86: Fix overflow bug with wmemchr-sse2 and wmemchr-avx2 [BZ #27974]\n- x86: Optimize strlen-avx2.S\n- x86: Optimize memchr-evex.S\n- x86-64: Fix an unknown vector operation in memchr-evex.S\n- x86-64: Move strlen.S to multiarch/strlen-vec.S\n- x86-64: Add wcslen optimize for sse4.1\n- x86: Fix overflow bug in wcsnlen-sse4_1 and wcsnlen-avx2 [BZ #27974]\n- x86: Optimize strlen-evex.S\n- String: Add overflow tests for strnlen, memchr, and strncat [BZ #27974]\n- x86-64: Require BMI2 for __strlen_evex and __strnlen_evex\n- x86: Check RTM_ALWAYS_ABORT for RTM [BZ #28033]\n- x86: Black list more Intel CPUs for TSX [BZ #27398]\n- x86: Remove wcsnlen-sse4_1 from wcslen ifunc-impl-list [BZ #28064]\n- x86-64: Test strlen and wcslen with 0 in the RSI register [BZ #28064]\n",null,[],[],[],[14],{"_key":15},"CVE-2021-3999",[],[],[19],{"_key":15},"2022-02-08T16:27:38Z","2026-04-16T04:24:05.951745Z",{"cisa_kev":23,"cisa_ransomware":23,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[25,31],{"url":26,"sources":27,"tags":29},"https://advisories.mageia.org/MGASA-2022-0052.html",[28],"osv_mageia",[30],"Advisory",{"url":32,"sources":33,"tags":34},"https://bugs.mageia.org/show_bug.cgi?id=29935",[28],[35],"REPORT",[],[],[],[40],{"ecosystem":41,"name":42,"vendor":43,"product":42,"cpe_part":9,"purl_type":44,"purl_namespace":43,"purl_name":42,"source":9,"versions":45},"Mageia","glibc","mageia","rpm",[46],{"version":47,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":50,"version_end_type":51,"fixed_in":9},"lt2_32_25_mga8",true,"ecosystem","2.32-25.mga8","excluding"]
