CVE-2020-27618
First published: Fri Feb 26 2021(Updated: )
GNU C Library (aka glibc or libc6) is vulnerable to a denial of service, caused by an error when processing some invalid inputs from several IBM character sets in the iconv function. By sending invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, IBM1399 encodings, a local authenticated attacker could exploit this vulnerability to cause the application to enter into an infinite loop.
