An old inffast.c optimization turns out to not be optimal anymore with modern compilers, and furthermore was not compliant with the C standard, for which decrementing a pointer before its allocated memory is undefined.

Last updated 14 January 2026
A flaw was found in the Apache Commons Configuration, where it uses a third-party library to process YAML files, which by default, allows the instantiation of classes if the YAML includes special statements. Apache Commons Configuration versions 2.2, 2.3, 2.4, 2.5, 2.6 did not change the default settings of this library. If a YAML file was loaded from an untrusted source, it could load and execute code out of the control of the host application.
FasterXML jackson-databind 2.x before 2.9.7 might allow remote attackers to execute arbitrary code by leveraging failure to block the blaze-ds-opt and blaze-ds-core classes from polymorphic deserialization.
Vulnerability in the Net Service component of Oracle Database Server. Supported versions that are affected are 23.4.0-23.26.2. Difficult to exploit vulnerability allows unauthenticated attacker with network access via TLS to compromise Net Service. While the vulnerability is in Net Service, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Net Service. CVSS 3.1 Base Score 9.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H).
Stack-based buffer overflow in Oracle Net Services for Oracle Database Server 9i release 2 and earlier allows attackers to execute arbitrary code via a "CREATE DATABASE LINK" query containing a connect string with a long USING parameter.
Multiple buffer overflows in Oracle 9i Database release 2, Release 1, 8i, 8.1.7, and 8.0.6 allow remote attackers to execute arbitrary code via (1) a long conversion string argument to the TOTIMESTAMPTZ function, (2) a long time zone argument to the TZOFFSET function, or (3) a long DIRECTORY parameter to the BFILENAME function.
Buffer overflow in ORACLE.EXE for Oracle Database Server 9i, 8i, 8.1.7, and 8.0.6 allows remote attackers to execute arbitrary code via a long username that is provided during login, as exploitable through client applications that perform their own authentication, as demonstrated using LOADPSP.
A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 through 2.9.10. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the commons-dbcp (1.4) jar in the classpath, and an attacker can find an RMI service endpoint to access, it is possible to make the service execute a malicious payload. This issue exists because of org.apache.commons.dbcp.datasources.SharedPoolDataSource and org.apache.commons.dbcp.datasources.PerUserPoolDataSource mishandling.
A deserialization flaw was discovered in the jackson-databind in versions before 2.8.10 and 2.9.1, which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper. This issue extends the previous flaw CVE-2017-7525 by blacklisting more classes that could be used maliciously.
