| Insertion of sensitive information into externally-accessible file or directory in Windows Storage allows an authorized attacker to disclose information locally. |
| In the Linux kernel, the following vulnerability has been resolved:
ufs: validate cylinder group metadata before caching it
ufs_read_cylinder() copies the cylinder group index and the rotor
positions straight from the on-disk group and caches them without any
check:
ucpi->c_cgx = fs32_to_cpu(sb, ucg->cg_cgx);
ucpi->c_rotor = fs32_to_cpu(sb, ucg->cg_rotor);
ucpi->c_frotor = fs32_to_cpu(sb, ucg->cg_frotor);
ucpi->c_irotor = fs32_to_cpu(sb, ucg->cg_irotor);
They are then used as indices during allocation and free:
- c_cgx indexes the cylinder summary array as
UFS_SB(sb)->fs_cs(ucpi->c_cgx), so a value past s_ncg writes a 32
bit count outside the s_csp allocation.
- c_frotor becomes a bitmap scan start, start = c_frotor >> 3, and
then length = ((s_fpg + 7) >> 3) - start. A start beyond the block
bitmap wraps the unsigned length to a huge value, so ubh_scanc()
walks far past the cylinder group buffers. c_irotor drives the
inode bitmap the same way.
A crafted image can set any of these freely, turning an ordinary
allocation into an out of bounds access.
Reject a cylinder group whose recorded index does not match the group
being read, or whose rotors fall outside the group, before the metadata
is cached. Valid filesystems keep cg_cgx equal to the group number and
the rotors within the group, so only malformed images are rejected. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/gud: validate TV mode names before creating enum property
The GUD protocol returns TV mode names as fixed-size
GUD_CONNECTOR_TV_MODE_NAME_LEN entries and requires each name to be
NUL-terminated.
gud_connector_add_tv_mode() currently passes each fixed-size entry
directly to drm_mode_create_tv_properties_legacy(), which eventually
reaches drm_property_add_enum() and strlen(). If a device returns an
entry without a terminating NUL byte, strlen() reads past the end of
the slot and can run beyond the allocated buffer, triggering an
out-of-bounds read.
Validate that each returned TV mode name contains a NUL terminator
within its fixed-size slot before passing it to the DRM property code.
If a malformed entry is found, reject the device response with -EIO.
This fixes the out-of-bounds read without changing the handling of
valid devices, and avoids silently truncating malformed protocol data. |
| Velociraptor stores the compiled VQL in the hunt object internally to avoid having to recompile the artifacts for each endpoint in the hunt. Although the field "compiled_collector_args" is an internal field, Velociraptor allowed the field to be set from a user API call. This allows another user who can schedule a hunt (minimal role of "investigator" ) to set the compiled VQL statements for the hunt bypassing any ACL checks that would normally be applied.
This flaw can then be escalated to allow the "investigator" user to run arbitrary VQL statements as an administrator user on the Velociraptor server. |
| A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS#11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure. |
| Buffer over-read vulnerability in Apache Tomcat Native during the TLS handshake permits a malicious user to trigger a DoS via a JVM crash.
This issue affects Apache Tomcat Native: from 2.0.0 through 2.0.15, from 1.3.0 through 1.3.8. Earlier, unsupported versions may also be affected.
Users are recommended to upgrade to version 1.3.9 or 2.0.16, which fix the issue. |
| Buffer over-read in Windows Encrypting File System (EFS) allows an authorized attacker to disclose information locally. |
| Transient DOS when processing authentication frames with invalid FILS information element header lengths. |
| Memory Corruption when multiple threads issue concurrent IOCTL requests to the device control handler due to improper synchronization and race conditions. |
| Transient DOS when processing a channel map with insufficient used channels and adaptive frequency hopping is fully enabled. |
| Transient DOS while parsing frame during channel usage. |
| Information Disclosure when a pointer is reused after being deallocated. |
| Buffer Over-read vulnerability in RTI Connext Professional (Core Libraries) allows Overread Buffers. This issue affects Connext Professional: from 7.4.0 before 7.7.0, from 7.0.0 before 7.3.1.1, from 6.1.0 before 6.1.2.34, from 6.0.0 before 6.0.*, from 5.3.0 before 5.3.*, from 5.2.0 before 5.2.*, from 4.3x before 5.1.*. |
| Buffer Over-read, Off-by-one Error vulnerability in RTI Connext Professional (Core Libraries) allows File Manipulation, Overread Buffers. This issue affects Connext Professional: from 7.4.0 before 7.6.0, from 7.0.0 before 7.3.0.8, from 6.1.0 before 6.1.2.26, from 6.0.0 before 6.0.1.43, from 5.3.0 before 5.3.*, from 5.2.0 before 5.2.*, from 4.4a before 5.1.*. |
| Buffer over-read in Windows Message Queuing Queue Manager allows an unauthorized attacker to disclose information over a network. |
| Buffer over-read in Windows Volume Manager Extension Driver allows an authorized attacker to elevate privileges locally. |
| Buffer over-read in Windows Win32K allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Overlay Filter allows an authorized attacker to disclose information over a network. |
| In the Linux kernel, the following vulnerability has been resolved:
platform/x86: dell-wmi-base: Fix handling of ultra performance key
The commit message of commit 5fbd827eb9c2 ("platform/x86: dell-wmi: Recognise or support new switches")
states that the ultra performance key contains additional data
after the type and code fields. The event data passed to
dell_wmi_process_key() is already parsed, so "buffer" already
starts after those two fields.
Use the correct index for accessing the first data field to avoid
a potential buffer overread. |
| An out-of-bounds read issue was addressed with improved input validation. This issue is fixed in macOS Golden Gate 27. Mounting a maliciously crafted exFAT volume may cause unexpected system termination or kernel memory disclosure. |
