Descriptions
The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid input sequences in the ISO-2022-JP-3 encoding, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service.
La función iconv en la biblioteca GNU C (también se conoce como glibc o libc6) versiones 2.32 y anteriores, cuando procesa secuencias de entrada no válidas en la codificación ISO-2022-JP-3, se produce un fallo una aserción en la ruta del código y aborta el programa, potencialmente resultando en una denegación de servicio
A flaw was found in glibc's iconv() functionality. This flaw allows an attacker capable of supplying a crafted sequence of characters to an application using iconv() to convert from ISO-2022-JP-3 to cause an assertion failure. The highest threat from this vulnerability is to system availability.
