CVE-2016-10228

The iconv program in the GNU C Library when invoked with multiple suffixes in the destination encoding (TRANSLATE or IGNORE) along with the -c option, enters an infinite loop when processing invalid multi-byte input sequences, leading to a denial of service.

CVE-2019-19126

On the x86-64 architecture, the GNU C Library fails to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program.

CVE-2019-25013

The iconv feature in the GNU C Library, when processing invalid multi-byte input sequences in the EUC-KR encoding, may have a buffer over-read.

CVE-2020-10029

The GNU C Library could overflow an on-stack buffer during range reduction if an input to an 80-bit long double function contains a non-canonical bit pattern, a seen when passing a 0x5d414141414141410000 value to sinl on x86 targets. This is related to sysdeps/ieee754/ldbl-96/e_rem_pio2l.c.

CVE-2020-1752

A use-after-free vulnerability introduced in glibc was found in the way the tilde expansion was carried out. Directory paths containing an initial tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path that, when processed by the glob function, would potentially lead to arbitrary code execution.

CVE-2020-27618

The iconv function in the GNU C Library, when processing invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 encodings, fails to advance the input state, which could lead to an infinite loop in applications, resulting in a denial of service, a different vulnerability from CVE-2016-10228.

CVE-2020-6096

An exploitable signed comparison vulnerability exists in the ARMv7 memcpy() implementation of GNU glibc. Calling memcpy() (on ARMv7 targets that utilize the GNU glibc implementation) with a negative value for the num parameter results in a signed comparison vulnerability. If an attacker underflows the num parameter to memcpy(), this vulnerability could lead to undefined behavior such as writing to out-of-bounds memory and potentially remote code execution. Furthermore, this memcpy() implementation allows for program execution to continue in scenarios where a segmentation fault or crash should have occurred. The dangers occur in that subsequent execution and iterations of this code will be executed with this corrupted data.

CVE-2021-27645

The nameserver caching daemon (nscd) in the GNU C Library, when processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in degraded service or Denial of Service on the local system. This is related to ... [Please see the references for more information on the vulnerabilities]");
