glibc vulnerabilities
Details

Jan Engelhardt, Tavis Ormandy, and others discovered that the GNU C Library iconv feature incorrectly handled certain input sequences. An attacker could possibly use this issue to cause the GNU C Library to hang or crash, resulting in a denial of service. (CVE-2021-3326)

It was discovered that the GNU C Library nscd daemon incorrectly handled certain netgroup lookups. An attacker could possibly use this issue to cause the GNU C Library to crash, resulting in a denial of service. (CVE-2021-35942)
