|---|---|---|---|---|---|
| CVE-2026-21977 | Low | 2026-01-20 | Not applicable | No public exploit | Vulnerability in the Oracle Zero Data Loss Recovery Appliance Software product of Oracle Zero Data Loss Recovery Appliance (component: Security). Supported versions that are affected are 23.1.0-23.1.202509. Difficult to exploit vulnerability allows unauthenticated attacker with network access via Oracle Net to compromise Oracle Zero Data Loss Recovery Appliance Software. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle Zero Data Loss Recovery Appliance Software accessible data. CVSS 3.1 Base Score 3.1 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N). |

Supported versions that are affected are 9.0.0-9.5.0. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of MySQL Server. CVSS 3.1 Base Score 2.7 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L). |

The supported version that is affected is 8.8. Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where Oracle ZFS Storage Appliance Kit executes to compromise Oracle ZFS Storage Appliance Kit. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle ZFS Storage Appliance Kit accessible data. CVSS 3.1 Base Score 2.3 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N). |
| CVE-2025-13837 | Low | 2025-12-01 | Not applicable | No public exploit | When loading a plist file, the plistlib module reads data in size specified by the file itself, meaning a malicious file can cause OOM and DoS issues |
| CVE-2025-6075 | Low | 2025-10-31 | Not applicable | No public exploit | If the value passed to os.path.expandvars() is user-controlled a performance degradation is possible when expanding environment variables. |
| CVE-2025-8961 | Low | 2025-08-14 | Not applicable | Proof of concept only | A weakness has been identified in LibTIFF 4.7.0. This affects the function main of the file tiffcrop.c of the component tiffcrop. Executing manipulation can lead to memory corruption. The attack can only be executed locally. The exploit has been made available to the public and could be exploited. |
| CVE-2025-8732 | Low | 2025-08-08 | Not applicable | No public exploit | A vulnerability was found in libxml2 up to 2.14.5. It has been declared as problematic. This vulnerability affects the function xmlParseSGMLCatalog of the component xmlcatalog. The manipulation leads to uncontrolled recursion. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted at the moment. The code maintainer explains, that "[t]he issue can only be triggered with untrusted SGML catalogs and it makes absolutely no sense to use untrusted catalogs. I also doubt that anyone is still using SGML catalogs at all." |
| CVE-2025-8176 | Low | 2025-07-26 | Not applicable | Proof of concept only | A vulnerability was found in LibTIFF up to 4.7.0. It has been declared as critical. This vulnerability affects the function get_histogram of the file tools/tiffmedian.c. The manipulation leads to use after free. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used. The patch is identified as fe10872e53efba9cc36c66ac4ab3b41a839d5172. It is recommended to apply a patch to fix this issue. |
| CVE-2025-4878 | Low | 2025-07-22 | Not applicable | No public exploit | A vulnerability was found in libssh, where an uninitialized variable exists under certain conditions in the privatekey_from_file() function. This flaw can be triggered if the file specified by the filename doesn't exist and may lead to possible signing failures or heap corruption. |
| CVE-2025-53643 | Low | 2025-07-14 | Not applicable | No public exploit | AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.12.14, the Python parser is vulnerable to a request smuggling vulnerability due to not parsing trailer sections of an HTTP request. If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. Version 3.12.14 contains a patch for this issue. |
