CVE-2026-4046

Опубликовано: 30 мар. 2026
Источник: redhat
CVSS3: 5.3

Описание

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.

A flaw was found in glibc, the GNU C Library. A remote attacker could exploit this vulnerability by providing specially crafted inputs using the IBM1390 or IBM1399 character sets to the iconv() function. This could lead to an assertion failure, causing the application to crash and resulting in a Denial of Service (DoS).

Отчет

The availability impact posed by this flaw is limited on Red Hat systems. The affected iconv() function has been separated out into a an independent package (glibc-gconv-extra) and is not used in system critical software. Some applications do rely on this package and may be affected, but they are either interactive applications or are configured to restart in the event of a crash.

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.
