<p>An update that solves seven vulnerabilities and has two security fixes can now be installed.</p>
<h2>Description:</h2>
<p>This update for proftpd fixes the following issues:</p>
<ul>
<li>Authenticated SFTP sessions can overflow the SFTP packet buffer (bsc#1271096).</li>
<li>CVE-2026-35025: access control bypass allows authenticated FTP users to circumvent Directory ACL restrictions by
prefixing paths with <code>/proc/self/root</code> in the RNFR command handler (bsc#1269065).</li>
<li>CVE-2026-42167: <code>mod_sql</code> allows remote attackers to execute arbitrary code via a username when there is logging of
<code>USER</code> requests with an expansion such as <code>%U</code> and the SQL backend allows <code>comman</code> (bsc#1263183).</li>
<li>CVE-2026-44331: SQL injection in <code>sqltab_fetch_clients_cb()</code> in <code>contrib/mod_wrap2_sql.c</code> triggered via crafted domain
name from reverse DNS lookup (bsc#1264262).</li>
<li>CVE-2026-53994: heap-based buffer overflow reachable by an authenticated SFTP user can lead to denial of service and
memory corruption (bsc#1271946).</li>
<li>CVE-2026-63090: heap-based buffer overflow in the <code>mod_sftp</code> module can lead to arbitrary code execution via crafted
SFTP packet fragments (bsc#1271944).</li>
<li>CVE-2026-63091: signed integer overflow in the <code>mod_sftp</code> module's SCP size-record parser can lead to ASLR bypass via
a crafted file size value of <code>UINT64_MAX</code> (bsc#1271945).</li>
<li>CVE-2026-119147: authorization bypass in the <code>mod_sftp</code> copy-file extension handler allows SFTP users to copy any
readable file to a new path in write-denied directories (bsc#1289272).</li>
<li>Integer overflow via client-provided file size for SCP uploads (bsc#1271097).</li>
</ul>
