RockyLinux 10 : glibc (RLSA-2026:76781)

critical Nessus Plugin ID 368075

Synopsis

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

Description

The remote RockyLinux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:76781 advisory.

 * glibc: Process abort due to invalid memory in wordexp (CVE-2026-6368)

 * glibc: Denial of Service via stack exhaustion during tilde expansion (CVE-2026-6791)

 * glibc: Buffer Overflow in strfmon right-justification padding (CVE-2026-19499)

 * glibc: Fix out-of-bounds array write in tdelete (CVE-2026-19542)

 Bug Fix(es) and Enhancement(s):

 * The iconv utility no longer returns exit status 1 after a successful //TRANSLIT transliteration

 * A counter overflow in __wcsmbs_clone_conv that occurred when setlocale was called has been fixed

 * A fcntl.h header conflict when compiling on Rocky Linux 10 has been resolved

 * Minor documentation improvements have been picked up from upstream

Tenable has extracted the preceding description block directly from the RockyLinux 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 packages.
