CVSS v3.1 |
| Integer underflow in wolfSSL packet sniffer <= 5.8.4 allows an attacker to cause a buffer overflow in the AEAD decryption path by injecting a TLS record shorter than the explicit IV plus authentication tag into traffic inspected by ssl_DecodePacket. The underflow wraps a 16-bit length to a large value that is passed to AEAD decryption routines, causing heap buffer overflow and a crash. An unauthenticated attacker can trigger this remotely via malformed TLS Application Data records. |
| A vulnerability was identified in Tenda F456 1.0.0.5. The impacted element is the function fromP2pListFilter of the file /goform/P2pListFilter. The manipulation of the argument menufacturer/Go leads to buffer overflow. The attack is possible to be carried out remotely. The exploit is publicly available and might be used. |
| A heap-buffer-overflow vulnerability exists in wolfSSL's wolfSSL_d2i_SSL_SESSION() function. When deserializing session data with SESSION_CERTS enabled, certificate and session id lengths are read from an untrusted input without bounds validation, allowing an attacker to overflow fixed-size buffers and corrupt heap memory. A maliciously crafted session would need to be loaded from an external source to trigger this vulnerability. Internal sessions were not vulnerable. |
| Two buffer overflow vulnerabilities existed in the wolfSSL CRL parser when parsing CRL numbers: a heap-based buffer overflow could occur when improperly storing the CRL number as a hexadecimal string, and a stack-based overflow for sufficiently sized CRL numbers. With appropriately crafted CRLs, either of these out of bound writes could be triggered. Note this only affects builds that specifically enable CRL support, and the user would need to load a CRL from an untrusted source. |
| A weakness has been identified in Tenda F456 1.0.0.5. The impacted element is the function fromaddressNat of the file /goform/addressNat. Executing a manipulation of the argument menufacturer/Go can lead to buffer overflow. The attack may be performed from remote. The exploit has been made available to the public and could be used for attacks. |
| A security vulnerability has been detected in Tenda F456 1.0.0.5. This affects the function fromRouteStatic of the file /goform/RouteStatic. The manipulation of the argument page leads to buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed publicly and may be used. |
| A vulnerability was detected in Tenda F456 1.0.0.5. This impacts the function fromSafeMacFilter of the file /goform/SafeMacFilter. The manipulation of the argument page results in buffer overflow. It is possible to launch the attack remotely. The exploit is now public and may be used. |
| When generating an ICMP Destination Unreachable or Packet Too Big response, the handler copies a portion of the original packet into the ICMP error body using the IP header's self-declared total length (ip_tot_len for IPv4, ip6_plen for IPv6) without validating it against the actual packet buffer size. A VM can send a short packet with an inflated IP length field that triggers an ICMP error (e.g., by hitting a reject ACL), causing ovn-controller to read heap memory beyond the valid packet data and include it in the ICMP response sent back to the VM. |
| A flaw has been found in Tenda F456 1.0.0.5. Affected is the function SafeEmailFilter of the file /goform/SafeEmailFilter. This manipulation of the argument page causes buffer overflow. The attack can be initiated remotely. The exploit has been published and may be used. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix off-by-8 bounds check in check_wsl_eas()
The bounds check uses (u8 *)ea + nlen + 1 + vlen as the end of the EA
name and value, but ea_data sits at offset sizeof(struct
smb2_file_full_ea_info) = 8 from ea, not at offset 0. The strncmp()
later reads ea->ea_data[0..nlen-1] and the value bytes follow at
ea_data[nlen+1..nlen+vlen], so the actual end is ea->ea_data + nlen + 1
+ vlen. Isn't pointer math fun?
The earlier check (u8 *)ea > end - sizeof(*ea) only guarantees the
8-byte header is in bounds, but since the last EA is placed within 8
bytes of the end of the response, the name and value bytes are read past
the end of iov.
Fix this mess all up by using ea->ea_data as the base for the bounds
check.
An "untrusted" server can use this to leak up to 8 bytes of kernel heap
into the EA name comparison and influence which WSL xattr the data is
interpreted as. |
| A security vulnerability has been detected in Tenda F456 1.0.0.5. Impacted is the function fromDhcpListClient of the file /goform/DhcpListClient of the component httpd. Such manipulation of the argument page leads to buffer overflow. The attack can be launched remotely. The exploit has been disclosed publicly and may be used. |
| A flaw was found in OVN (Open Virtual Network). A remote attacker, by sending crafted DHCPv6 (Dynamic Host Configuration Protocol for IPv6) SOLICIT packets with an inflated Client ID length, could cause the ovn-controller to read beyond the bounds of a packet. This out-of-bounds read can lead to the disclosure of sensitive information stored in heap memory, which is then returned to the attacker's virtual machine port. |
| A vulnerability was detected in Tenda F456 1.0.0.5. The affected element is the function formQuickIndex of the file /goform/QuickIndex of the component httpd. Performing a manipulation of the argument mit_linktype results in buffer overflow. The attack may be initiated remotely. The exploit is now public and may be used. |
| A flaw has been found in Tenda F456 1.0.0.5. The impacted element is the function fromNatlimitof of the file /goform/Natlimit of the component httpd. Executing a manipulation can lead to buffer overflow. The attack may be launched remotely. The exploit has been published and may be used. |
| A vulnerability has been found in Tenda F456 1.0.0.5. This affects the function fromWrlclientSet of the file /goform/WrlclientSet of the component httpd. The manipulation leads to buffer overflow. Remote exploitation of the attack is possible. The exploit has been disclosed to the public and may be used. |
| 1-byte OOB heap read in wc_PKCS7_DecodeEnvelopedData via zero-length encrypted content. A vulnerability existed in wolfSSL 5.8.4 and earlier, where a 1-byte out-of-bounds heap read in wc_PKCS7_DecodeEnvelopedData could be triggered by a crafted CMS EnvelopedData message with zero-length encrypted content. Note that PKCS7 support is disabled by default. |
| Heap buffer overflow in CertFromX509 via AuthorityKeyIdentifier size confusion. A heap buffer overflow occurs when converting an X.509 certificate internally due to incorrect size handling of the AuthorityKeyIdentifier extension. |
| Heap buffer overflow in DTLS 1.3 ACK message processing. A remote attacker can send a crafted DTLS 1.3 ACK message that triggers a heap buffer overflow. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: validate EaNameLength in smb2_get_ea()
smb2_get_ea() reads ea_req->EaNameLength from the client request and
passes it directly to strncmp() as the comparison length without
verifying that the length of the name really is the size of the input
buffer received.
Fix this up by properly checking the size of the name based on the value
received and the overall size of the request, to prevent a later
strncmp() call to use the length as a "trusted" size of the buffer.
Without this check, uninitialized heap values might be slowly leaked to
the client. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: require 3 sub-authorities before reading sub_auth[2]
parse_dacl() compares each ACE SID against sid_unix_NFS_mode and on
match reads sid.sub_auth[2] as the file mode. If sid_unix_NFS_mode is
the prefix S-1-5-88-3 with num_subauth = 2 then compare_sids() compares
only min(num_subauth, 2) sub-authorities so a client SID with
num_subauth = 2 and sub_auth = {88, 3} will match.
If num_subauth = 2 and the ACE is placed at the very end of the security
descriptor, sub_auth[2] will be 4 bytes past end_of_acl. The
out-of-band bytes will then be masked to the low 9 bits and applied as
the file's POSIX mode, probably not something that is good to have
happen.
Fix this up by forcing the SID to actually carry a third sub-authority
before reading it at all. |
