An update that solves seven vulnerabilities and has two security fixes can now
be installed.

## Description:

This update for proftpd fixes the following issues:

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