Description
The iconv() function in the GNU C Library versions 2.43 and earlier may crash due to an assertion failure when converting inputs from the IBM1390 or IBM1399 character sets, which may be used to remotely crash an application. This vulnerability can be trivially mitigated by removing the IBM1390 and IBM1399 character sets from systems that do not need them.
Analysis
Remote denial of service in GNU C Library (glibc) 2.43 and earlier allows unauthenticated remote attackers to crash applications via malformed input during character set conversion from IBM1390 or IBM1399 encodings. The vulnerability triggers an assertion failure in the iconv() function with high attack reliability (CVSS 7.5, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). …
