CVE-2025-38180 2 Debian, Linux 2 Debian Linux, Linux Kernel 2025-12-18 N/A 7.8 HIGH
In the Linux kernel, the following vulnerability has been resolved: net: atm: fix /proc/net/atm/lec handling /proc/net/atm/lec must ensure safety against dev_lec[] changes. It appears it had dev_put() calls without prior dev_hold(), leading to imbalance and UAF.
CVE-2023-51385 2 Debian, Openbsd 2 Debian Linux, Openssh 2025-12-18 N/A 6.5 MEDIUM
In ssh in OpenSSH before 9.6, OS command injection might occur if a user name or host name has shell metacharacters, and this name is referenced by an expansion token in certain situations. For example, an untrusted Git repository can have a submodule with shell metacharacters in a user name or host name.
CVE-2021-3177 5 Debian, Fedoraproject, Netapp and 2 more 10 Debian Linux, Fedora, Active Iq Unified Manager and 7 more 2025-12-18 7.5 HIGH 9.8 CRITICAL
Python 3.x through 3.9.1 has a buffer overflow in PyCArg_repr in _ctypes/callproc.c, which may lead to remote code execution in certain Python applications that accept floating-point numbers as untrusted input, as demonstrated by a 1e300 argument to c_double.from_param. This occurs because sprintf is used unsafely.
CVE-2021-27803 3 Debian, Fedoraproject, W1.fi 3 Debian Linux, Fedora, Wpa Supplicant 2025-12-18 5.4 MEDIUM 7.5 HIGH
A vulnerability was discovered in how p2p/p2p_pd.c in wpa_supplicant before 2.10 processes P2P (Wi-Fi Direct) provision discovery requests. It could result in denial of service or other impact (potentially execution of arbitrary code), for an attacker within radio range.
CVE-2019-6111 10 Apache, Canonical, Debian and 7 more 27 Mina Sshd, Ubuntu Linux, Debian Linux and 24 more 2025-12-18 5.8 MEDIUM 5.9 MEDIUM
An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file).
CVE-2021-3426 6 Debian, Fedoraproject, Netapp and 3 more 10 Debian Linux, Fedora, Cloud Backup and 7 more 2025-12-18 2.7 LOW 5.7 MEDIUM
There's a flaw in Python 3's pydoc. A local or adjacent attacker who discovers or is able to convince another local or adjacent user to start a pydoc server could access the server and use it to disclose sensitive information belonging to the other user that they would not normally be able to access. The highest risk of this flaw is to data confidentiality. This flaw affects Python versions before 3.8.9, Python versions before 3.9.3 and Python versions before 3.10.0a7.
CVE-2019-3859 5 Debian, Fedoraproject, Libssh2 and 2 more 5 Debian Linux, Fedora, Libssh2 and 2 more 2025-12-18 6.4 MEDIUM 9.1 CRITICAL
An out of bounds read flaw was discovered in libssh2 before 1.8.1 in the _libssh2_packet_require and _libssh2_packet_requirev functions. A remote attacker who compromises a SSH server may be able to cause a Denial of Service or read data in the client memory.
CVE-2021-4189 4 Debian, Netapp, Python and 1 more 5 Debian Linux, Ontap Select Deploy Administration Utility, Python and 2 more 2025-12-17 N/A 5.3 MEDIUM
A flaw was found in Python, specifically in the FTP (File Transfer Protocol) client library in PASV (passive) mode. The issue is how the FTP client trusts the host from the PASV response by default. This flaw allows an attacker to set up a malicious FTP server that can trick FTP clients into connecting back to a given IP address and port. This vulnerability could lead to FTP client scanning ports, which otherwise would not have been possible.
CVE-2021-28957 5 Debian, Fedoraproject, Lxml and 2 more 5 Debian Linux, Fedora, Lxml and 2 more 2025-12-17 4.3 MEDIUM 6.1 MEDIUM
An XSS vulnerability was discovered in python-lxml's clean module versions before 4.6.3. When disabling the safe_attrs_only and forms arguments, the Cleaner class does not remove the formaction attribute allowing for JS to bypass the sanitizer. A remote attacker could exploit this flaw to run arbitrary JS code on users who interact with incorrectly sanitized HTML. This issue is patched in lxml 4.6.3.
CVE-2021-28831 3 Busybox, Debian, Fedoraproject 3 Busybox, Debian Linux, Fedora 2025-12-17 5.0 MEDIUM 7.5 HIGH
decompress_gunzip.c in BusyBox through 1.32.1 mishandles the error bit on the huft_build result pointer, with a resultant invalid free or segmentation fault, via malformed gzip data.
CVE-2021-23336 6 Debian, Djangoproject, Fedoraproject and 3 more 12 Debian Linux, Django, Fedora and 9 more 2025-12-17 4.0 MEDIUM 5.9 MEDIUM
The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before 3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and urllib.parse.parse_qs by using a vector called parameter cloaking. When the attacker can separate query parameters using a semicolon (;), they can cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server. This can result in malicious requests being cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and therefore would not include it in a cache key of an unkeyed parameter.
CVE-2019-20388 6 Debian, Fedoraproject, Netapp and 3 more 31 Debian Linux, Fedora, Cloud Backup and 28 more 2025-12-17 5.0 MEDIUM 7.5 HIGH
xmlSchemaPreRun in xmlschemas.c in libxml2 2.9.10 allows an xmlSchemaValidateStream memory leak.
CVE-2018-20685 9 Canonical, Debian, Fujitsu and 6 more 30 Ubuntu Linux, Debian Linux, M10-1 and 27 more 2025-12-17 2.6 LOW 5.3 MEDIUM
In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side.
CVE-2018-1125 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2025-12-17 5.0 MEDIUM 7.5 HIGH
procps-ng before version 3.3.15 is vulnerable to a stack buffer overflow in pgrep. This vulnerability is mitigated by FORTIFY, as it involves strncat() to a stack-allocated string. When pgrep is compiled with FORTIFY (as on Red Hat Enterprise Linux and Fedora), the impact is limited to a crash.
CVE-2018-15473 7 Canonical, Debian, Netapp and 4 more 24 Ubuntu Linux, Debian Linux, Aff Baseboard Management Controller and 21 more 2025-12-17 5.0 MEDIUM 5.3 MEDIUM
OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c.
CVE-2018-14465 7 Apple, Debian, F5 and 4 more 7 Mac Os X, Debian Linux, Traffix Signaling Delivery Controller and 4 more 2025-12-17 5.0 MEDIUM 7.5 HIGH
The RSVP parser in tcpdump before 4.9.3 has a buffer over-read in print-rsvp.c:rsvp_obj_print().
CVE-2016-1762 6 Apple, Canonical, Debian and 3 more 15 Iphone Os, Mac Os X, Safari and 12 more 2025-12-17 5.8 MEDIUM 8.1 HIGH
The xmlNextChar function in libxml2 before 2.9.4 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted XML document.
CVE-2020-27783 6 Debian, Fedoraproject, Lxml and 3 more 8 Debian Linux, Fedora, Lxml and 5 more 2025-12-17 4.3 MEDIUM 6.1 MEDIUM
A XSS vulnerability was discovered in python-lxml's clean module. The module's parser didn't properly imitate browsers, which caused different behaviors between the sanitizer and the user's page. A remote attacker could exploit this flaw to run arbitrary HTML/JS code.
CVE-2025-37949 2 Debian, Linux 2 Debian Linux, Linux Kernel 2025-12-17 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: xenbus: Use kref to track req lifetime Marek reported seeing a NULL pointer fault in the xenbus_thread callstack: BUG: kernel NULL pointer dereference, address: 0000000000000000 RIP: e030:__wake_up_common+0x4c/0x180 Call Trace: <TASK> __wake_up_common_lock+0x82/0xd0 process_msg+0x18e/0x2f0 xenbus_thread+0x165/0x1c0 process_msg+0x18e is req->cb(req). req->cb is set to xs_wake_up(), a thin wrapper around wake_up(), or xenbus_dev_queue_reply(). It seems like it was xs_wake_up() in this case. It seems like req may have woken up the xs_wait_for_reply(), which kfree()ed the req. When xenbus_thread resumes, it faults on the zero-ed data. Linux Device Drivers 2nd edition states: "Normally, a wake_up call can cause an immediate reschedule to happen, meaning that other processes might run before wake_up returns." ... which would match the behaviour observed. Change to keeping two krefs on each request. One for the caller, and one for xenbus_thread. Each will kref_put() when finished, and the last will free it. This use of kref matches the description in Documentation/core-api/kref.rst
CVE-2025-37951 2 Debian, Linux 2 Debian Linux, Linux Kernel 2025-12-17 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Add job to pending list if the reset was skipped When a CL/CSD job times out, we check if the GPU has made any progress since the last timeout. If so, instead of resetting the hardware, we skip the reset and let the timer get rearmed. This gives long-running jobs a chance to complete. However, when `timedout_job()` is called, the job in question is removed from the pending list, which means it won't be automatically freed through `free_job()`. Consequently, when we skip the reset and keep the job running, the job won't be freed when it finally completes. This situation leads to a memory leak, as exposed in [1] and [2]. Similarly to commit 704d3d60fec4 ("drm/etnaviv: don't block scheduler when GPU is still active"), this patch ensures the job is put back on the pending list when extending the timeout.
