CVE-2021-21781 – kernel: arm: SIGPAGE information disclosure vulnerability
https://notcve.org/view.php?id=CVE-2021-21781
An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel v5.4.66 and v5.4.54. The latest version (5.11-rc4) seems to still be vulnerable. A userland application can read the contents of the sigpage, which can leak kernel memory contents. An attacker can read a process’s memory at a specific offset to trigger this vulnerability. This was fixed in kernel releases: 4.14.222 4.19.177 5.4.99 5.10.17 5.11 Se presenta una vulnerabilidad de divulgación de información en la funcionalidad ARM SIGPAGE del Kernel de Linux versiones v5.4.66 y v5.4.54. • https://talosintelligence.com/vulnerability_reports/TALOS-2021-1243 https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2021-21781 https://bugzilla.redhat.com/show_bug.cgi?id=1981950 • CWE-908: Use of Uninitialized Resource •
CVE-2021-32827 – Arbitrary code execution in MockServer
https://notcve.org/view.php?id=CVE-2021-32827
MockServer is open source software which enables easy mocking of any system you integrate with via HTTP or HTTPS. An attacker that can trick a victim into visiting a malicious site while running MockServer locally, will be able to run arbitrary code on the MockServer machine. With an overly broad default CORS configuration MockServer allows any site to send cross-site requests. Additionally, MockServer allows you to create dynamic expectations using Javascript or Velocity templates. Both engines may allow an attacker to execute arbitrary code on-behalf of MockServer. • https://securitylab.github.com/advisories/GHSL-2021-059-mockserver https://www.oracle.com/security-alerts/cpujan2022.html • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

CVE-2021-36374 – Apache Ant ZIP, and ZIP based, archive denial of service vulerability
https://notcve.org/view.php?id=CVE-2021-36374
When reading a specially crafted ZIP archive, or a derived formats, an Apache Ant build can be made to allocate large amounts of memory that leads to an out of memory error, even for small inputs. This can be used to disrupt builds using Apache Ant. Commonly used derived formats from ZIP archives are for instance JAR files and many office files. Apache Ant prior to 1.9.16 and 1.10.11 were affected. Cuando se lee un archivo ZIP especialmente diseñado, o un formato derivado, se puede hacer que una compilación de Apache Ant asigne grandes cantidades de memoria que conlleva a un error de falta de memoria, incluso para entradas pequeñas. • https://ant.apache.org/security.html https://lists.apache.org/thread.html/r27919fd4db07c487239c1d9771f480d89ce5ee2750aa9447309b709a%40%3Ccommits.groovy.apache.org%3E https://lists.apache.org/thread.html/r544c9e8487431768465b8b2d13982c75123109bd816acf839d46010d%40%3Ccommits.groovy.apache.org%3E https://lists.apache.org/thread.html/rad36f470647c5a7c02dd78c9973356d2840766d132b597b6444e373a%40%3Cnotifications.groovy.apache.org%3E https://lists.apache.org/thread.html/rdd5412a5b9a25aed2a02c3317052d38a97128314d50bc1ed36e81d38%40%3Cuser.ant.apache.org%3E https://lists.apache.org/thre • CWE-130: Improper Handling of Length Parameter Inconsistency •
