Описание
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.
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.
Отчет
Exploitation of this flaw would cause the application to halt execution. It relies on processing untrusted input in the ISO-2022-JP-3 encoding or ISO-2022-JP-3 being used as a MIME charset in applications using iconv.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
