7 security issues in bookworm high

There are 7 open security issues in bookworm.

6 important issues:

CVE-2026-53994: ProFTPD mod_sftp contains a heap-based buffer overflow reachable by an authenticated SFTP user. The fxp_packet_read() function accepts the attacker-supplied 32-bit big-endian SFTP packet length without a minimum sanity check. A value of 0 causes an unsigned subtraction elsewhere in the read path to underflow to approximately 4 GB. That oversized request reaches the core memory allocator, where the rounded size is computed in size_t but passed to new_block() as a 32-bit int; the low 32 bits of 0x100000000 are 0, so new_block() returns a small (~512-byte) block while the caller is told it received ~4 GB. The subsequent fill loop then streams attacker-controlled bytes past the end of the 544-byte allocation, producing an attacker-controlled heap buffer overflow. An authenticated user can crash the per-connection ProFTPD session child on demand with a single malformed SFTP packet (packet_len=0 followed by a body greater than approximately 544 bytes), producing reliable authenticated remote denial of service. Depending on heap layout and adjacent allocations, heap metadata corruption and further consequences beyond denial of service may be possible, though only denial of service is demonstrated by the supplied proof of concept.
CVE-2026-63090: ProFTPD before 1.3.9c and 1.3.10rc3 contains a heap-based buffer overflow vulnerability in the mod_sftp module that allows authenticated low-privilege attackers to achieve arbitrary code execution by sending crafted SFTP packet fragments exceeding the 16 KB reassembly buffer in the fxp.c component. Attackers can supply oversized fragments to trigger an incorrectly conditioned reallocation, corrupt pool freelist metadata, overwrite the root_fs BSS global pointer to reference a fake filesystem struct, and redirect pr_fsio_stat() to system() via a crafted RENAME request.
CVE-2026-63091: ProFTPD before 1.3.9c and 1.3.10rc3 contains a signed integer overflow vulnerability in the mod_sftp module's SCP size-record parser that allows authenticated low-privilege attackers to bypass ASLR by sending a crafted file size value of UINT64_MAX, which results in a negative off_t value. Attackers can exploit the subsequent conversion to uint32_t, causing an approximately 4 GB requested read length and forcing the server to read beyond the end of the SSH channel data and write overread process memory into the uploaded file. In tested configurations, the disclosed data contains libc, libcrypto, and PIE pointers sufficient to derive their randomized base addresses, thereby bypassing ASLR and enabling reliable exploitation of memory corruption vulnerabilities in the same process.
CVE-2026-119146: ProFTPD before 1.3.9e and 1.3.10rc5 contains a buffer overflow vulnerability in the mod_rewrite int:utf8trans RewriteMap that allows remote attackers to overwrite static buffers. Attackers can send FTP command arguments longer than 1024 bytes, without authentication if pre-login commands are rewritten, to corrupt session memory and crash the session.
CVE-2026-119147: ProFTPD before 1.3.9e and 1.3.10rc5 contains an authorization bypass in the mod_sftp copy-file extension handler that skips Limit WRITE checks for new destination files. Authenticated SFTP users can copy any readable file to a new path in write-denied directories, creating files where uploads are forbidden.
CVE-2026-119364: ProFTPD through 1.3.9e and 1.3.10rc1 through 1.3.10rc4 contains a link-following vulnerability in mod_copy that allows authenticated FTP users to bypass Limit WRITE restrictions via symlinks. Attackers can place a symlink in a writable directory and use SITE COPY or SITE CPTO to overwrite files in write-denied locations.

1 issue postponed or untriaged:

CVE-2026-44331: (needs triaging) In ProFTPD through 1.3.9a before 7666224, a SQL injection vulnerability in sqltab_fetch_clients_cb() in contrib/mod_wrap2_sql.c allows a remote attacker to inject arbitrary SQL commands via a crafted domain name that is accessed in a reverse DNS lookup. When "UseReverseDNS on" is enabled, the attacker-supplied hostname is passed unescaped into SQL queries. The character restrictions of DNS names may affect exploitability.

5 security issues in bullseye high

There are 5 open security issues in bullseye.

5 important issues:

CVE-2026-42167: mod_sql in ProFTPD before 1.3.9a allows remote attackers to execute arbitrary code via a username, in scenarios where there is logging of USER requests with an expansion such as %U, and the SQL backend allows commands (e.g., COPY TO PROGRAM).
