CVSS: 9.8EPSS: 0%CPEs: 9EXPL: 0CVE-2021-3520 – lz4: memory corruption due to an integer overflow bug caused by memmove argument
https://notcve.org/view.php?id=CVE-2021-3520
There's a flaw in lz4. An attacker who submits a crafted file to an application linked with lz4 may be able to trigger an integer overflow, leading to calling of memmove() on a negative size argument, causing an out-of-bounds write and/or a crash. The greatest impact of this flaw is to availability, with some potential impact to confidentiality and integrity as well. Se presenta un fallo en lz4. Un atacante que envíe un archivo diseñado hacia una aplicación enlazada con lz4 puede ser capaz de desencadenar un desbordamiento de enteros, conllevando una llamada de la función memmove() con un argumento de tamaño negativo, causando una escritura fuera de límites y/o un bloqueo. • https://bugzilla.redhat.com/show_bug.cgi?id=1954559 https://security.netapp.com/advisory/ntap-20211104-0005 https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpuoct2021.html https://access.redhat.com/security/cve/CVE-2021-3520 • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2019-17543
LZ4 before 1.9.2 has a heap-based buffer overflow in LZ4_write32 (related to LZ4_compress_destSize), affecting applications that call LZ4_compress_fast with a large input. (This issue can also lead to data corruption.) NOTE: the vendor states "only a few specific / uncommon usages of the API are at risk." LZ4 versiones anteriores a 1.9.2, presenta un desbordamiento de búfer en la región heap de la memoria en LZ4_write32 (relacionado con la función LZ4_compress_destSize), que afecta a las aplicaciones que llaman a LZ4_compress_fast con una entrada larga. (Este problema también puede conllevar a la corrupción de datos). • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00069.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00070.html https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=15941 https://github.com/lz4/lz4/compare/v1.9.1...v1.9.2 https://github.com/lz4/lz4/issues/801 https://github.com/lz4/lz4/pull/756 https://github.com/lz4/lz4/pull/760 https://lists.apache.org/thread.html/25015588b770d67470b7ba7ea49a305d6735dd7f00eabe7d50ec1e17%40%3Cissues.arrow&# • CWE-787: Out-of-bounds Write •
