CVE-2018-16840 3 Canonical, Haxx, Redhat 3 Ubuntu Linux, Curl, Jboss Core Services 2026-04-16 9.8 Critical
A heap use-after-free flaw was found in curl versions from 7.59.0 through 7.61.1 in the code related to closing an easy handle. When closing and cleaning up an 'easy' handle in the `Curl_close()` function, the library code first frees a struct (without nulling the pointer) and might then subsequently erroneously write to a struct field within that already freed struct.
CVE-2022-39177 3 Bluez, Canonical, Debian 3 Bluez, Ubuntu Linux, Debian Linux 2026-04-15 8.8 High
BlueZ before 5.59 allows physically proximate attackers to cause a denial of service because malformed and invalid capabilities can be processed in profiles/audio/avdtp.c.
CVE-2022-39176 3 Bluez, Canonical, Debian 3 Bluez, Ubuntu Linux, Debian Linux 2026-04-15 8.8 High
BlueZ before 5.59 allows physically proximate attackers to obtain sensitive information because profiles/audio/avrcp.c does not validate params_len.
CVE-2018-1000301 5 Canonical, Debian, Haxx and 2 more 15 Ubuntu Linux, Debian Linux, Curl and 12 more 2026-04-15 9.1 Critical
curl version curl 7.20.0 to and including curl 7.59.0 contains a CWE-126: Buffer Over-read vulnerability in denial of service that can result in curl can be tricked into reading data beyond the end of a heap based buffer used to store downloaded RTSP content.. This vulnerability appears to have been fixed in curl < 7.20.0 and curl >= 7.60.0.
CVE-2018-16839 4 Canonical, Debian, Haxx and 1 more 4 Ubuntu Linux, Debian Linux, Curl and 1 more 2026-04-15 N/A
Curl versions 7.33.0 through 7.61.1 are vulnerable to a buffer overrun in the SASL authentication code that may lead to denial of service.
CVE-2018-16842 4 Canonical, Debian, Haxx and 1 more 6 Ubuntu Linux, Debian Linux, Curl and 3 more 2026-04-15 N/A
Curl versions 7.14.1 through 7.61.1 are vulnerable to a heap-based buffer over-read in the tool_msgs.c:voutf() function that may result in information exposure and denial of service.
CVE-2018-14618 4 Canonical, Debian, Haxx and 1 more 6 Ubuntu Linux, Debian Linux, Libcurl and 3 more 2026-04-15 N/A
curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The internal function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how large temporary storage area to allocate from the heap. The length value is then subsequently used to iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit size_t, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31 bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the intended very huge one, making the use of that buffer end up in a heap buffer overflow. (This bug is almost identical to CVE-2017-8816.)
CVE-2018-16890 8 Canonical, Debian, F5 and 5 more 11 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 8 more 2026-04-15 7.5 High
libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds.
CVE-2019-3822 7 Canonical, Debian, Haxx and 4 more 17 Ubuntu Linux, Debian Linux, Libcurl and 14 more 2026-04-15 9.8 Critical
libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening. This output data can grow larger than the local buffer if very large 'nt response' data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server. Such a 'large value' needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes from the NTLMv2 type-2 response header.
CVE-2019-3823 6 Canonical, Debian, Haxx and 3 more 9 Ubuntu Linux, Debian Linux, Libcurl and 6 more 2026-04-15 N/A
libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to `smtp_endofresp()` isn't NUL terminated and contains no character ending the parsed number, and `len` is set to 5, then the `strtol()` call reads beyond the allocated buffer. The read contents will not be returned to the caller.
CVE-2019-9928 3 Canonical, Debian, Gstreamer 3 Ubuntu Linux, Debian Linux, Gstreamer 2026-03-17 N/A
GStreamer before 1.16.0 has a heap-based buffer overflow in the RTSP connection parser via a crafted response from a server, potentially allowing remote code execution.
CVE-2025-13350 1 Canonical 1 Ubuntu Linux 2026-03-09 N/A
Ubuntu Linux 6.8 GA retains the legacy AF_UNIX garbage collector but backports upstream commit 8594d9b85c07 ("af_unix: Don’t call skb_get() for OOB skb"). When orphaned MSG_OOB sockets hit unix_gc(), the garbage collector still calls kfree_skb() as if OOB SKBs held two references; on Ubuntu Linux 6.8 (Noble Numbat) kernel tree, they have only the queue reference, so the buffer is freed while still reachable and subsequent queue walks dereference freed memory, yielding a reliable local privilege escalation (LPE) caused by a use-after-free (UAF). Ubuntu builds that have already taken the new GC stack from commit 4090fa373f0e, and mainline Linux kernels shipping that infrastructure are unaffected because they no longer execute the legacy collector path. This issue affects Ubuntu Linux from 6.8.0-56.58 before 6.8.0-84.84.
CVE-2025-32463 6 Canonical, Debian, Opensuse and 3 more 8 Ubuntu Linux, Debian Linux, Leap and 5 more 2026-02-26 9.3 Critical
Sudo before 1.9.17p1 allows local users to obtain root access because /etc/nsswitch.conf from a user-controlled directory is used with the --chroot option.
CVE-2019-12749 3 Canonical, Freedesktop, Redhat 5 Ubuntu Linux, Dbus, Enterprise Linux and 2 more 2026-02-13 7.1 High
dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent client connection came from an attacker-chosen uid, allowing authentication bypass.
CVE-2025-33208 2 Canonical, Nvidia 3 Ubuntu Linux, Tao, Tao Toolkit 2026-01-30 8.8 High
NVIDIA TAO contains a vulnerability where an attacker may cause a resource to be loaded via an uncontrolled search path. A successful exploit of this vulnerability may lead to escalation of privileges, data tampering, denial of service, information disclosure.
CVE-2018-14634 6 Canonical, F5, Linux and 3 more 35 Ubuntu Linux, Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager and 32 more 2026-01-27 N/A
An integer overflow flaw was found in the Linux kernel's create_elf_tables() function. An unprivileged local user with access to SUID (or otherwise privileged) binary could use this flaw to escalate their privileges on the system. Kernel versions 2.6.x, 3.10.x and 4.14.x are believed to be vulnerable.
CVE-2025-6966 3 Canonical, Debian, Ubuntu 4 Python-apt, Ubuntu Linux, Debian Linux and 1 more 2026-01-07 5.5 Medium
NULL pointer dereference in TagSection.keys() in python-apt on APT-based Linux systems allows a local attacker to cause a denial of service (process crash) via a crafted deb822 file with a malformed non-UTF-8 key.
CVE-2018-19787 3 Canonical, Debian, Lxml 3 Ubuntu Linux, Debian Linux, Lxml 2025-12-18 6.1 Medium
An issue was discovered in lxml before 4.2.5. lxml/html/clean.py in the lxml.html.clean module does not remove javascript: URLs that use escaping, allowing a remote attacker to conduct XSS attacks, as demonstrated by "j a v a s c r i p t:" in Internet Explorer. This is a similar issue to CVE-2014-3146.
CVE-2018-1124 6 Canonical, Debian, Opensuse and 3 more 13 Ubuntu Linux, Debian Linux, Leap and 10 more 2025-12-18 7.8 High
procps-ng before version 3.3.15 is vulnerable to multiple integer overflows leading to a heap corruption in file2strvec function. This allows a privilege escalation for a local attacker who can create entries in procfs by starting processes, which could result in crashes or arbitrary code execution in proc utilities run by other users.
CVE-2018-20685 9 Canonical, Debian, Fujitsu and 6 more 30 Ubuntu Linux, Debian Linux, M10-1 and 27 more 2025-12-17 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.
