https://notcve.org/view.php?id=CVE-2021-29338
Integer Overflow in OpenJPEG v2.4.0 allows remote attackers to crash the application, causing a Denial of Service (DoS). This occurs when the attacker uses the command line option "-ImgDir" on a directory that contains 1048576 files. Integer Overflow en OpenJPEG versión v2.4.0 permite a atacantes remotos bloquear la aplicación, causando una denegación de servicio (DoS). Esto ocurre cuando el atacante usa la opción de línea de comando "-ImgDir" en un directorio que contiene 1048576 archivos There is a flaw in the opj2_compress program in openjpeg2. An attacker who is able to submit a large number of image files to be processed in a directory by opj2_compress, could trigger a heap out-of-bounds write due to an integer overflow, which is caused by the large number of image files. • https://github.com/uclouvain/openjpeg/issues/1338 https://lists.debian.org/debian-lts-announce/2022/04/msg00006.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EZ54FGM2IGAP4AWSJ22JKHOPHCR3FGYU https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QB6AI7CWXWMEDZIQY4LQ6DMIEXMDOHUP https://security.gentoo.org/glsa/202209-04 https://access.redhat.com/security/cve/CVE-2021-29338 https://bugzilla.redhat.com/show_bug.cgi?id=1950101 • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
