CVSS: 5.5EPSS: 0%CPEs: 73EXPL: 0CVE-2021-36373 – Apache Ant TAR archive denial of service vulnerability
https://notcve.org/view.php?id=CVE-2021-36373
When reading a specially crafted TAR archive an Apache Ant build can be made to allocate large amounts of memory that finally leads to an out of memory error, even for small inputs. This can be used to disrupt builds using Apache Ant. Apache Ant prior to 1.9.16 and 1.10.11 were affected. Cuando se lee un archivo TAR especialmente diseñado, se puede hacer que una compilación de Apache Ant asigne grandes cantidades de memoria que finalmente conlleva a un error de falta de memoria, incluso para entradas pequeñas. Esto puede ser usado para interrumpir las compilaciones usando Apache Ant. • 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/r54afdab05e01de970649c2d91a993f68a6b00cd73e6e34e16c832d46%40%3Cuser.ant.apache.org%3E https://lists.apache.org/thread.html/rad36f470647c5a7c02dd78c9973356d2840766d132b597b6444e373a%40%3Cnotifications.groovy.apache.org%3E https://lists.apache.org/thre • CWE-130: Improper Handling of Length Parameter Inconsistency CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.8EPSS: 0%CPEs: 27EXPL: 0CVE-2021-3612 – kernel: joydev: zero size passed to joydev_handle_JSIOCSBTNMAP()
https://notcve.org/view.php?id=CVE-2021-3612
An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in versions before 5.9-rc1, in the way the user calls ioctl JSIOCSBTNMAP. This flaw allows a local user to crash the system or possibly escalate their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Se ha encontrado un fallo de escritura en memoria fuera de límites en el kernel de Linux joystick devices subsystem en versiones anteriores a 5.9-rc1, en la manera en que el usuario llama a la ioctl JSIOCSBTNMAP. Este fallo permite a un usuario local bloquear el sistema o posiblemente escalar sus privilegios en el sistema. • https://bugzilla.redhat.com/show_bug.cgi?id=1974079 https://lists.debian.org/debian-lts-announce/2021/10/msg00010.html https://lists.debian.org/debian-lts-announce/2021/12/msg00012.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YKGI562LFV5MESTMVTCG5RORSBT6NGBN https://lore.kernel.org/linux-input/20210620120030.1513655-1-avlarkin82%40gmail.com https://security.netapp.com/advisory/ntap-20210805-0005 https://www.oracle.com/security-alerts/cpujul2022.html https:& • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2021-22897
curl 7.61.0 through 7.76.1 suffers from exposure of data element to wrong session due to a mistake in the code for CURLOPT_SSL_CIPHER_LIST when libcurl is built to use the Schannel TLS library. The selected cipher set was stored in a single "static" variable in the library, which has the surprising side-effect that if an application sets up multiple concurrent transfers, the last one that sets the ciphers will accidentally control the set used by all transfers. In a worst-case scenario, this weakens transport security significantly. curl versiones 7.61.0 hasta 7.76.1, sufre de exposición de un elemento de datos a una sesión equivocada debido a un error en el código para la función CURLOPT_SSL_CIPHER_LIST cuando libcurl es construído para usar la biblioteca TLS de Schannel. El ajuste de cifrado seleccionado se almacenaba en una única variable "static" en la biblioteca, lo que tiene el sorprendente efecto secundario de que si una aplicación establece múltiples transferencias concurrentes, la última que ajusta los cifrados controlará accidentalmente el ajuste usado por todas las transferencias.

CVSS: 7.5EPSS: 0%CPEs: 13EXPL: 1CVE-2021-33560 – libgcrypt: mishandles ElGamal encryption because it lacks exponent blinding to address a side-channel attack against mpi_powm
https://notcve.org/view.php?id=CVE-2021-33560
Libgcrypt before 1.8.8 and 1.9.x before 1.9.3 mishandles ElGamal encryption because it lacks exponent blinding to address a side-channel attack against mpi_powm, and the window size is not chosen appropriately. This, for example, affects use of ElGamal in OpenPGP. Libgcrypt versiones anteriores a 1.8.8 y versiones 1.9.x anteriores a 1.9.3, maneja inapropiadamente el cifrado de ElGamal porque carece de cegado de exponentes para hacer frente a un ataque de canal lateral contra la función mpi_powm, y el tamaño de la ventana no se elige apropiadamente. Esto, por ejemplo, afecta el uso de ElGamal en OpenPGP. A side-channel attack flaw was found in the way libgcrypt implemented Elgamal encryption. • https://github.com/IBM/PGP-client-checker-CVE-2021-33560 https://dev.gnupg.org/T5305 https://dev.gnupg.org/T5328 https://dev.gnupg.org/T5466 https://dev.gnupg.org/rCe8b7f10be275bcedb5fc05ed4837a89bfd605c61 https://lists.debian.org/debian-lts-announce/2021/06/msg00021.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BKKTOIGFW2SGN3DO2UHHVZ7MJSYN4AAB https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/R7OAPCUGPF3VLA7QAJUQSL255D4ITVTL • CWE-203: Observable Discrepancy CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
