Description

A vulnerability in GNU C Library (eglibc) versions 2.3 to 2.44 causes an infinite loop when converting crafted SHIFT_JISX0213 input if 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 in GNU C Library (eglibc) affects versions from 2.3 up to 2.44 and is triggered by conversion of crafted SHIFT_JISX0213 input. The flaw causes the conversion process to hang indefinitely due to an infinite loop when the output buffer is insufficiently sized. This affects the SHIFT_JISX0213 character set, which is rarely used. Red Hat has released a security advisory with updates to glibc packages that address this issue.

Potential Impact

The vulnerability causes the affected system to hang indefinitely during conversion of specific SHIFT_JISX0213 input, potentially leading to denial of service conditions. Since the affected character set is uncommon, the likelihood of exploitation is reduced. There are no known exploits in the wild at this time.

Mitigation Recommendations

A patch is available from Red Hat as part of their Hardened Images RPMs update. Users should apply the updated glibc packages as per the Red Hat advisory RHSA-2026:61737 to remediate this issue.
