Description

A vulnerability in GNU C Library (eglibc) versions 2.3 to 2.44 causes the conversion of crafted SHIFT_JISX0213 input to hang indefinitely due to an infinite loop triggered when the output buffer is too small. This flaw affects the SHIFT_JISX0213 character set, which is not commonly used. A patch is available to fix this issue.

Technical Analysis

The vulnerability exists in the GNU C Library (eglibc) versions 2.3 through 2.44 and affects the conversion process of SHIFT_JISX0213 encoded input to UCS-4 or the internal wide character encoding. When processing certain crafted sequences that decode to two code points, if the output buffer is insufficient to hold both, the converter enters an infinite loop causing the application to hang. This issue is specific to the SHIFT_JISX0213 character set. A related but separate issue affects EUC_JISX0213 and is tracked under CVE-2026-80489. Red Hat has released a patch to address this vulnerability.

Potential Impact

The vulnerability can cause applications that perform character set conversions involving SHIFT_JISX0213 to hang indefinitely due to an infinite loop in the conversion process. This may lead to denial of service conditions in affected applications. The character set involved is not commonly used, which may limit the exposure.

Mitigation Recommendations

A patch is available from Red Hat to address this vulnerability. Users should apply the official updates to the affected glibc packages as provided in the Red Hat Security Advisory RHSA-2026:61737. No additional mitigation steps are indicated by the vendor.
