Oracle Linux: CVE-2021-29338: ELSA-2021-4251: openjpeg2 security update (MODERATE) (Multiple Advisories)
Description
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. 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. The greatest threat posed by this flaw is to confidentiality, integrity, and availability.
