CVE-2020-25647 [HIGH] CWE-787 CVE-2020-25647: A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors a A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a bypass of the Secure Boot mechanism. The high

CVE-2019-2534 [HIGH] CVE-2019-2534: Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Replication). Sup Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Replication). Supported versions that are affected are 5.6.42 and prior, 5.7.24 and prior and 8.0.13 and prior.

CVE-2023-5633 [HIGH] CVE-2023-5633: The reference count changes made as part of the CVE-2023-33951 and CVE-2023-33952 fixes exposed a us The reference count changes made as part of the CVE-2023-33951 and CVE-2023-33952 fixes exposed a use-after-free flaw in the way memory objects were handled when they were being used to store a surface. When running inside a VMware guest with 3D acceleration enabled, a local, unprivileged user could potentially use this flaw to escalate their privileges.

CVE-2026-6384 [HIGH] CWE-120 CVE-2026-6384: A flaw was found in gimp. This buffer overflow vulnerability in the GIF image loading component's `R A flaw was found in gimp. This buffer overflow vulnerability in the GIF image loading component's `ReadJeffsImage` function allows an attacker to write beyond an allocated buffer by processing a specially crafted GIF file. This can lead to a denial of service or potentially arbitrary code execution.

CVE-2026-58384 [HIGH] CWE-190 CVE-2026-58384: A flaw was found in GIMP's PSD parser. An integer overflow in read_RLE_channel() can cause an unders A flaw was found in GIMP's PSD parser. An integer overflow in read_RLE_channel() can cause an undersized heap allocation for the RLE row-length table, after which subsequent per-row writes corrupt heap memory. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution.

CVE-2022-3787 [HIGH] CWE-285 CVE-2022-3787: A vulnerability was found in the device-mapper-multipath. The device-mapper-multipath allows local u A vulnerability was found in the device-mapper-multipath. The device-mapper-multipath allows local users to obtain root access, exploited alone or in conjunction with CVE-2022-41973. Local users that are able to write to UNIX domain sockets can bypass access controls and manipulate the multipath setup. This issue occurs because an attacker can repeat a

CVE-2026-42170 [HIGH] CWE-131 CVE-2026-42170: A heap-based buffer overflow vulnerability exists in the GIMP DDS (DirectDraw Surface) file parser. A heap-based buffer overflow vulnerability exists in the GIMP DDS (DirectDraw Surface) file parser. When a crafted DDS file declares a D3D9 pixel format but sets a lower bits-per-pixel (bpp) value in the header, the loader allocates an undersized heap buffer. Subsequent pixel data consumption at the real format's stride causes a write past the heap buf

CVE-2008-4302 [MEDIUM] CWE-667 CVE-2008-4302: fs/splice.c in the splice subsystem in the Linux kernel before 2.6.22.2 does not properly handle a f fs/splice.c in the splice subsystem in the Linux kernel before 2.6.22.2 does not properly handle a failure of the add_to_page_cache_lru function, and subsequently attempts to unlock a page that was not locked, which allows local users to cause a denial of service (kernel BUG and system crash), as demonstrated by the fio I/O tool.

CVE-2026-59850 [HIGH] CWE-416 CVE-2026-59850: A flaw was found in libssh. If data packets are processed after a channel is closed, channel data ca A flaw was found in libssh. If data packets are processed after a channel is closed, channel data callbacks can be invoked after the associated data has already been freed, leading to crashes or possible use-after-free conditions.

CVE-2026-3260 [HIGH] CWE-770 CVE-2026-3260: A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending an HTTP A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending an HTTP GET request containing multipart/form-data content. If the underlying application processes parameters using methods like `getParameterMap()`, the server prematurely parses and stores this content to disk. This could lead to resource exhaustion, potentiall

CVE-2021-20254 [MEDIUM] CWE-125 CVE-2021-20254: A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix group ids (gids). The code that performs this had a flaw that could allow it to read data beyond the end of the array in the case where a negative cache entry had been added to the mapping cache. This could cause the calling code to return those v

CVE-2019-17024 [HIGH] CWE-787 CVE-2019-17024: Mozilla developers reported memory safety bugs present in Firefox 71 and Firefox ESR 68.3. Some of t Mozilla developers reported memory safety bugs present in Firefox 71 and Firefox ESR 68.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72.

CVE-2026-15370 [HIGH] CWE-121 CVE-2026-15370: A flaw was found in libssh. During SFTP server directory listing, the longname field is constructed A flaw was found in libssh. During SFTP server directory listing, the longname field is constructed with unsafe concatenation into a fixed-size stack buffer. When a client causes the server to list attacker-controlled filenames, sufficiently long names can overflow that stack buffer and may lead to crashes or possible code execution on the server.

CVE-2026-66338 [HIGH] CWE-444 CVE-2026-66338: A flaw was found in libsoup. The chunked transfer encoding parser uses a permissive parsing function A flaw was found in libsoup. The chunked transfer encoding parser uses a permissive parsing function for chunk sizes that silently accepts inputs violating RFC 9112, including leading whitespace, plus sign prefixes, and trailing invalid characters. When libsoup operates behind a strict frontend proxy, this parsing differential can be exploited to smug

CVE-2017-5436 [HIGH] CWE-787 CVE-2017-5436: An out-of-bounds write in the Graphite 2 library triggered with a maliciously crafted Graphite font. An out-of-bounds write in the Graphite 2 library triggered with a maliciously crafted Graphite font. This results in a potentially exploitable crash. This issue was fixed in the Graphite 2 library as well as Mozilla products. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.

CVE-2019-15166 [HIGH] CWE-120 CVE-2019-15166: lmp_print_data_link_subobjs() in print-lmp.c in tcpdump before 4.9.3 lacks certain bounds checks. lmp_print_data_link_subobjs() in print-lmp.c in tcpdump before 4.9.3 lacks certain bounds checks.

CVE-2023-4091 [MEDIUM] CWE-276 CVE-2023-4091: A vulnerability was discovered in Samba, where the flaw allows SMB clients to truncate files, even w A vulnerability was discovered in Samba, where the flaw allows SMB clients to truncate files, even with read-only permissions when the Samba VFS module "acl_xattr" is configured with "acl_xattr:ignore system acls = yes". The SMB protocol allows opening files when the client requests read-only access but then implicitly truncates the opened file to 0 b

CVE-2018-14463 [HIGH] CWE-125 CVE-2018-14463: The VRRP parser in tcpdump before 4.9.3 has a buffer over-read in print-vrrp.c:vrrp_print() for VRRP The VRRP parser in tcpdump before 4.9.3 has a buffer over-read in print-vrrp.c:vrrp_print() for VRRP version 2, a different vulnerability than CVE-2019-15167.
