CVE-2021-31872	Modificada	Crítica (9.8)	2.1%	—	Klibc Project Klibc Debian Linux	30/4/2021	17/6/2026	An issue was discovered in klibc before 2.0.9. Multiple possible integer overflows in the cpio command on 32-bit systems may result in a buffer overflow or other security impact.
CVE-2021-31871	Modificada	Alta (7.5)	1.9%	—	Klibc Project Klibc Debian Linux	30/4/2021	17/6/2026	An issue was discovered in klibc before 2.0.9. An integer overflow in the cpio command may result in a NULL pointer dereference on 64-bit systems.
CVE-2021-31870	Modificada	Crítica (9.8)	2.1%	—	Klibc Project Klibc Debian Linux	30/4/2021	17/6/2026	An issue was discovered in klibc before 2.0.9. Multiplication in the calloc() function may result in an integer overflow and a subsequent heap buffer overflow.
CVE-2011-1930	Modificada	Crítica (9.8)	21%	—	Klibc Project Klibc Debian Linux	14/11/2019	16/6/2026	In klibc 1.5.20 and 1.5.21, the DHCP options written by ipconfig to /tmp/net-$DEVICE.conf are not properly escaped. This may allow a remote attacker to send a specially crafted DHCP reply which could execute arbitrary code with the privileges of any process which sources DHCP options.
