Fedora 43 : glibc (2026-205d532069)

high Nessus Plugin ID 296551

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-205d532069 advisory.

 This update switches the currency symbol for Bulgaria to the Euro.

 Furthermore, it addresses several security vulnerabilities:

 * A crash when `wordexp` is used with `WRDE_REUSE` (CVE-2025-15281)
 * Information leakage from the stack if `getnetbyaddr` is called for the zero address (CVE-2026-0915)
 * An integer overflow in `memalign` and related functions if they are called with out-of-bounds size/alignment combinations (CVE-2026-0861)
 * `LD_PROFILE` is now ignored with a warning if `LD_PROFILE_OUTPUT` is not specified, rather than using the insecure `/var/tmp` default.


Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected glibc package.
