| Out-of-bounds read in Windows NTFS allows an authorized attacker to elevate privileges locally. |
| Out-of-bounds read in Windows NTFS allows an authorized attacker to disclose information over a network. |
| A flaw was found in sssd, specifically within the PAM (Pluggable Authentication Modules) responder's protocol v1 parser, pam_parse_in_data(). A local client with access to the PAM responder's UNIX socket can exploit this by negotiating protocol v1 and sending an empty or truncated PAM request body. This can trigger an out-of-bounds read, potentially causing the PAM responder to terminate or restart, leading to a local denial of service. |
| A flaw was found in the sssd NSS responder. This input validation vulnerability allows a local attacker, by sending specially crafted service lookup requests to the NSS responder's UNIX socket, to cause an out-of-bounds read. This out-of-bounds read may lead to a denial of service (DoS) by crashing the NSS responder process. While unprivileged local clients can typically reach the socket, there is no evidence of privilege escalation or reliable data disclosure. |
| A weakness has been identified in Matthias-Wandel jhead up to 3.3. This affects the function Get16u of the file exif.c of the component EXIF Parsing. This manipulation causes out-of-bounds read. The attack requires local access. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet. |
| An issue was discovered in the mirage-crypto-ec package before 2.3.0 for OCaml. There is an EC public key out-of-bounds read for compressed points. |
| An out-of-bounds read in the stbtt_GetGlyphShape component of nothings stb commit 31c1ad3 allows attackers to cause a Denial of Service (DoS) via sending a crafted TTF file. |
| In libxml2 before 2.15.4, xmlFAParsePosCharGroup has an out-of-bounds read, aka an out-of-bounds read in the NXT macro in xmlregexp. |
| Certain VLC media player builds in versions 3.0.0 through 3.0.23 contain a memory-safety vulnerability reachable when processing media from an attacker-controlled network source. Exploitation requires user interaction and may disclose a limited, layout-dependent amount of VLC process memory. Exposure depends on build configuration. |
| Out-of-bounds read in Microsoft Office Excel allows an unauthorized attacker to disclose information locally. |
| zstd-jni versions before 1.5.7-14 fail to validate offset and length parameters in the ZstdDictCompress constructor, allowing out-of-bounds memory reads. Attackers can supply untrusted offset or length values to read native heap memory into the compression dictionary, typically causing JVM crashes. |
| Buffer Over-read vulnerability in Apache HTTP Server via outbound OCSP requests to an attacker controlled OCSP server
This issue affects Apache HTTP Server: from 2.4.0 through 2.4.67.
Users are recommended to upgrade to version 2.4.68, which fixes the issue. |
| A flaw was found in gdk-pixbuf. This vulnerability allows a remote attacker to cause a heap out-of-bounds read by providing a specially crafted Apple Icon Image (.icns) file. The uncompress() function, which handles RLE-encoded ICNS icon data, fails to validate the source buffer's boundaries during decompression. This can lead to a denial of service, where the application crashes, or to information disclosure, potentially revealing sensitive data from adjacent memory. |
| In the Linux kernel, the following vulnerability has been resolved:
fpga: altera-cvp: Avoid out-of-bounds read in trailing byte write
The trailing byte path in altera_cvp_send_block() dereferences a u32
pointer even when only 1-3 bytes remain in the input buffer. If the buffer
ends at a page or scatterlist boundary, this can read past the valid image
data and fault.
Copy the remaining bytes into a zero-initialized u32 before writing the
final word so only valid bytes are read from the input buffer. |
| In the Linux kernel, the following vulnerability has been resolved:
lib/ucs2_string.c: fix out-of-bounds read in ucs2_strnlen()
Patch series "lib/ucs2_string.c: fix out-of-bounds read in
ucs2_strnlen()", v2.
This series fixes an off-by-one out-of-bounds read in ucs2_strnlen().
The first patch is the real fix, the second patch comes as a bonus and
fixes the code indentation.
This patch (of 2):
ucs2_strnlen() checks the current character before checking whether the
caller-provided maximum length has been reached. If the input is not
NUL-terminated within that bound, the loop can read one ucs2_char_t past
the limit.
Test the length before dereferencing to prevent an off-by-one
out-of-bounds read. |
| In the Linux kernel, the following vulnerability has been resolved:
ubifs: fix out-of-bounds read in signature length check
ubifs_sb_verify_signature() bounds the on-disk ubifs_sig_node->len field
before handing the signature payload to verify_pkcs7_signature(), but the
check has the wrong sign:
if (le32_to_cpu(signode->len) > snod->len + sizeof(struct ubifs_sig_node))
The signature bytes start sizeof(struct ubifs_sig_node) (UBIFS_SIG_NODE_SZ,
64 bytes) into the node, so the payload is at most
snod->len - sizeof(struct ubifs_sig_node)
bytes long. Adding the header size instead of subtracting it accepts a
declared length up to 2 * UBIFS_SIG_NODE_SZ larger than the node actually
holds -- past the end of c->sbuf, which is vmalloc(c->leb_size).
verify_pkcs7_signature() -> pkcs7_parse_message() -> asn1_ber_decoder()
is then handed that inflated length and reads beyond the allocation while
walking the DER headers. The node length comes straight from the mounted
image, so a crafted signed UBIFS image reaches this via
ubifs_read_superblock() before the signature is cryptographically checked.
snod->len is guaranteed to be >= UBIFS_SIG_NODE_SZ by the node scanner
(c->ranges[UBIFS_SIG_NODE].min_len == UBIFS_SIG_NODE_SZ), so the corrected
subtraction cannot underflow. Legitimately signed images are unaffected: a
correct superblock never declares a signature longer than the node it is
embedded in. |
| In the Linux kernel, the following vulnerability has been resolved:
nfsd: fix XDR padding calculation in ff_encode_getdeviceinfo
nfsd4_ff_encode_getdeviceinfo() computes the da_addr_body reservation
as 16 + netid_len + addr_len, but the subsequent xdr_encode_opaque()
calls emit 8 + round_up(netid_len, 4) + round_up(addr_len, 4) bytes.
The mismatch means the declared da_addr_body length exceeds the actual
encoded data by 2-8 bytes on every flexfile GETDEVICEINFO reply,
leaking stale reply-page content to the client and mis-aligning the
subsequent version list decode.
Use xdr_align_size() for each string length to match what
xdr_encode_opaque() actually writes. |
| In the Linux kernel, the following vulnerability has been resolved:
libceph: validate OSD extent maps before cursor advance
net/ceph/osd_client.c:osd_sparse_read() validates that the sparse-read
data length matches the summed extent lengths, but it does not validate
that each OSD-supplied extent is monotonic and lies inside the original
request range. A malformed authenticated OSD reply can advertise a
far-forward nonzero extent offset with a matching data length and make
the client advance the message-data cursor beyond the request buffer.
This reaches the BUG_ON(!*length) assertion in ceph_msg_data_next() from
the client receive path.
Impact: A malicious or compromised authenticated Ceph OSD peer can crash
a kernel Ceph client via a malformed sparse-read reply.
Reject sparse extent maps that overflow, move backwards, overlap, or
extend outside the original sparse-read request before advancing the
cursor.
[ idryomov: perform sparse_extent_map_valid() check a bit earlier,
in CEPH_SPARSE_READ_DATA_LEN instead of CEPH_SPARSE_READ_DATA_PRE
state ] |
