<p>An update that solves seven vulnerabilities can now be installed.</p>
<h2>Description:</h2>
<p>This update for busybox fixes the following issues:</p>
<ul>
<li>CVE-2026-88830: unit confusion in TLS Montgomery reduction buffer allocation causes a pre-authentication heap buffer
overflow when processing a crafted <code>ClientKeyExchange</code> message (bsc#1282575).</li>
<li>CVE-2026-88831: httpd silently fails open when IP deny rules contain invalid CIDR prefix lengths (bsc#1282550).</li>
<li>CVE-2026-88832: romfs volume ID parsing uses unbounded <code>strlen</code> on attacker-controlled metadata and allows for a heap
buffer overflow when crafted filesystem images are processed (bsc#1282576).</li>
<li>CVE-2026-88835: dpkg read_package_field() steps past NUL terminator, causing out-of-bounds read on malformed .deb
packages (bsc#1282551).</li>
<li>CVE-2026-88837: httpd misidentifies yescrypt password hashes as plaintext (bsc#1282552).</li>
<li>CVE-2026-88839: passwd/group parser writes heap pointers out of bounds due to stale tokenize() endpoint (bsc#1282568).</li>
<li>CVE-2026-88841: OOB read and silent memory corruption of the status file due to <code>write_status_file()</code> failing to reset
the <code>field_start</code> cursor between package stanzas (bsc#1282653).</li>
