The BGP parser in tcpdump before 4.9.3 has a buffer over-read in print-bgp.c:bgp_attr_print() (MP_REACH_NLRI).
CVE-2018-16228 6 Apple, Debian, Fedoraproject and 3 more 6 Mac Os X, Debian Linux, Fedora and 3 more 2025-12-03 5.0 MEDIUM 7.5 HIGH
The HNCP parser in tcpdump before 4.9.3 has a buffer over-read in print-hncp.c:print_prefix().
CVE-2020-27827 5 Fedoraproject, Lldpd Project, Openvswitch and 2 more 27 Fedora, Lldpd, Openvswitch and 24 more 2025-12-03 7.1 HIGH 7.5 HIGH
A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2019-15166 8 Apple, Canonical, Debian and 5 more 10 Mac Os X, Ubuntu Linux, Debian Linux and 7 more 2025-12-03 5.0 MEDIUM 1.6 LOW
lmp_print_data_link_subobjs() in print-lmp.c in tcpdump before 4.9.3 lacks certain bounds checks.
CVE-2021-33285 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2025-12-03 6.9 MEDIUM 7.8 HIGH
In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS attribute is supplied to the function ntfs_get_attribute_value, a heap buffer overflow can occur allowing for memory disclosure or denial of service. The vulnerability is caused by an out-of-bound buffer access which can be triggered by mounting a crafted ntfs partition. The root cause is a missing consistency check after reading an MFT record : the "bytes_in_use" field should be less than the "bytes_allocated" field. When it is not, the parsing of the records proceeds into the wild.
CVE-2021-20232 3 Fedoraproject, Gnu, Redhat 3 Fedora, Gnutls, Enterprise Linux 2025-12-03 7.5 HIGH 9.8 CRITICAL
A flaw was found in gnutls. A use after free issue in client_send_params in lib/ext/pre_shared_key.c may lead to memory corruption and other potential consequences.
CVE-2021-20197 4 Broadcom, Gnu, Netapp and 1 more 6 Brocade Fabric Operating System Firmware, Binutils, Cloud Backup and 3 more 2025-12-03 3.3 LOW 6.3 MEDIUM
There is an open race window when writing output in the following utilities in GNU binutils version 2.35 and earlier:ar, objcopy, strip, ranlib. When these utilities are run as a privileged user (presumably as part of a script updating binaries across different users), an unprivileged user can trick these utilities into getting ownership of arbitrary files through a symlink.
CVE-2021-3448 4 Fedoraproject, Oracle, Redhat and 1 more 4 Fedora, Communications Cloud Native Core Network Function Cloud Native Environment, Enterprise Linux and 1 more 2025-12-03 4.3 MEDIUM 4.0 MEDIUM
A flaw was found in dnsmasq in versions before 2.85. When configured to use a specific server for a given network interface, dnsmasq uses a fixed port while forwarding queries. An attacker on the network, able to find the outgoing port used by dnsmasq, only needs to guess the random transmission ID to forge a reply and get it accepted by dnsmasq. This flaw makes a DNS Cache Poisoning attack much easier. The highest threat from this vulnerability is to data integrity.
CVE-2021-3517 6 Debian, Fedoraproject, Netapp and 3 more 29 Debian Linux, Fedora, Active Iq Unified Manager and 26 more 2025-12-02 7.5 HIGH 8.6 HIGH
There is a flaw in the xml entity encoding functionality of libxml2 in versions before 2.9.11. An attacker who is able to supply a crafted file to be processed by an application linked with the affected functionality of libxml2 could trigger an out-of-bounds read. The most likely impact of this flaw is to application availability, with some potential impact to confidentiality and integrity if an attacker is able to use memory information to further exploit the application.
CVE-2021-39251 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2025-12-02 6.9 MEDIUM 7.8 HIGH
A crafted NTFS image can cause a NULL pointer dereference in ntfs_extent_inode_open in NTFS-3G < 2021.8.22.
CVE-2023-2603 4 Debian, Fedoraproject, Libcap Project and 1 more 4 Debian Linux, Fedora, Libcap and 1 more 2025-12-02 N/A 7.8 HIGH
A vulnerability was found in libcap. This issue occurs in the _libcap_strdup() function and can lead to an integer overflow if the input string is close to 4GiB.
CVE-2022-4904 3 C-ares Project, Fedoraproject, Redhat 4 C-ares, Fedora, Enterprise Linux and 1 more 2025-12-02 N/A 8.6 HIGH
A flaw was found in the c-ares package. The ares_set_sortlist is missing checks about the validity of the input string, which allows a possible arbitrary length stack overflow. This issue may cause a denial of service or a limited impact on confidentiality and integrity.
CVE-2022-2509 4 Debian, Fedoraproject, Gnu and 1 more 4 Debian Linux, Fedora, Gnutls and 1 more 2025-12-02 N/A 7.5 HIGH
A vulnerability found in gnutls. This security flaw happens because of a double free error occurs during verification of pkcs7 signatures in gnutls_pkcs7_verify function.
CVE-2022-4743 2 Libsdl, Redhat 2 Simple Directmedia Layer, Enterprise Linux 2025-11-25 N/A 7.5 HIGH
A potential memory leak issue was discovered in SDL2 in GLES_CreateTexture() function in SDL_render_gles.c. The vulnerability allows an attacker to cause a denial of service attack. The vulnerability affects SDL2 v2.0.4 and above. SDL-1.x are not affected.
CVE-2017-5408 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 5.0 MEDIUM 5.3 MEDIUM
Video files loaded video captions cross-origin without checking for the presence of CORS headers permitting such cross-origin use, leading to potential information disclosure for video captions. This vulnerability affects Firefox < 52, Firefox ESR < 45.8, Thunderbird < 52, and Thunderbird < 45.8.
CVE-2017-5410 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 7.5 HIGH 9.8 CRITICAL

CVE-2017-5390 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 7.5 HIGH 9.8 CRITICAL
The JSON viewer in the Developer Tools uses insecure methods to create a communication channel for copying and viewing JSON or HTTP headers data, allowing for potential privilege escalation. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.
CVE-2019-9810 2 Mozilla, Redhat 6 Firefox, Thunderbird, Enterprise Linux and 3 more 2025-11-25 6.8 MEDIUM 8.8 HIGH
