CVE-2021-35942 – glibc: Arbitrary read in wordexp()
https://notcve.org/view.php?id=CVE-2021-35942
The wordexp function in the GNU C Library (aka glibc) through 2.33 may crash or read arbitrary memory in parse_param (in posix/wordexp.c) when called with an untrusted, crafted pattern, potentially resulting in a denial of service or disclosure of information. This occurs because atoi was used but strtoul should have been used to ensure correct calculations. La función wordexp de la biblioteca GNU C (también se conoce como glibc) versiones hasta 2.33, puede bloquearse o leer memoria arbitraria en la función parse_param (en el archivo posix/wordexp.c) cuando se llama con un patrón diseñado que no es confiable, resultando en una denegación de servicio o divulgación de información. Esto ocurre porque atoi fue usado pero debería haber sido usado strtoul para asegurar cálculos correctos An integer overflow flaw was found in glibc that may result in reading of arbitrary memory when wordexp is used with a specially crafted untrusted regular expression input. • https://lists.debian.org/debian-lts-announce/2022/10/msg00021.html https://security.gentoo.org/glsa/202208-24 https://security.netapp.com/advisory/ntap-20210827-0005 https://sourceware.org/bugzilla/show_bug.cgi?id=28011 https://sourceware.org/git/?p=glibc.git%3Ba=commit%3Bh=5adda61f62b77384718b4c0d8336ade8f2b4b35c https://sourceware.org/glibc/wiki/Security%20Exceptions https://access.redhat.com/security/cve/CVE-2021-35942 https://bugzilla.redhat.com/show_bug.cgi?id=1977975 • CWE-190: Integer Overflow or Wraparound •

CVE-2021-34428 – jetty: SessionListener can prevent a session from being invalidated breaking logout
https://notcve.org/view.php?id=CVE-2021-34428
For Eclipse Jetty versions <= 9.4.40, <= 10.0.2, <= 11.0.2, if an exception is thrown from the SessionListener#sessionDestroyed() method, then the session ID is not invalidated in the session ID manager. On deployments with clustered sessions and multiple contexts this can result in a session not being invalidated. This can result in an application used on a shared computer being left logged in. Para Eclipse Jetty versiones anteriores a 9.4.40 incluyéndola, versiones anteriores a 10.0.2 incluyéndola, versiones anteriores a 11.0.2 incluyéndola, si es lanzada una excepción desde el método SessionListener#sessionDestroyed(), el ID de sesión no es invalidado en el administrador de ID de sesión. En despliegues con sesiones agrupadas y múltiples contextos esto puede resultar en que una sesión no sea invalidada. • https://github.com/eclipse/jetty.project/security/advisories/GHSA-m6cp-vxjx-65j6 https://lists.apache.org/thread.html/r67c4f90658fde875521c949448c54c98517beecdc7f618f902c620ec%40%3Cissues.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r8a1a332899a1f92c8118b0895b144b27a78e3f25b9d58a34dd5eb084%40%3Cnotifications.zookeeper.apache.org%3E https://lists.apache.org/thread.html/rbefa055282d52d6b58d29a79fbb0be65ab0a38d25f00bd29eaf5e6fd%40%3Cnotifications.zookeeper.apache.org%3E https://lists.apache.org/thread.html/rddbb4f8d5db23265bb63d14ef4b3723b438abc1589f877db11d35450%40%3Cissues.zo • CWE-613: Insufficient Session Expiration •
CVE-2021-33574 – glibc: mq_notify does not handle separately allocated thread attributes

CVE-2021-3517 – libxml2: Heap-based buffer overflow in xmlEncodeEntitiesInternal() in entities.c
https://notcve.org/view.php?id=CVE-2021-3517
There is a flaw in the xml entity encoding functionality of libxml2 in versions before 2.9.11. An attacker who is able to supply a crafted file to be processed by an application linked with the affected functionality of libxml2 could trigger an out-of-bounds read. The most likely impact of this flaw is to application availability, with some potential impact to confidentiality and integrity if an attacker is able to use memory information to further exploit the application. Se presenta un fallo en la funcionalidad xml entity encoding de libxml2 en versiones anteriores a 2.9.11. Un atacante que sea capaz de proporcionar un archivo diseñado para que sea procesado por una aplicación vinculada con la funcionalidad afectada de libxml2 podría desencadenar una lectura fuera de los límites. • https://bugzilla.redhat.com/show_bug.cgi?id=1954232 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/debian-lts-announce/2021/05/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BZOMV5J4PMZAORVT64BKLV6YIZAFDGX6 https://lists.fedoraproject.org/archives/list/pack • CWE-787: Out-of-bounds Write •
