https://notcve.org/view.php?id=CVE-2020-27823
A flaw was found in OpenJPEG’s encoder. This flaw allows an attacker to pass specially crafted x,y offset input to OpenJPEG to use during encoding. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Se encontró un fallo en el codificador de OpenJPEG. Este fallo permite a un atacante pasar una entrada de desplazamiento x,y especialmente diseñada a OpenJPEG para usarla durante la codificación. • https://bugzilla.redhat.com/show_bug.cgi?id=1905762 https://lists.debian.org/debian-lts-announce/2021/02/msg00011.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OQR4EWRFFZQDMFPZKFZ6I3USLMW6TKTP https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WJUPGIZE6A4O52EBOF75MCXJOL6MUCRV https://www.debian.org/security/2021/dsa-4882 https://access.redhat.com/security/cve/CVE-2020-27823 • CWE-20: Improper Input Validation CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

A flaw was found in OpenJPEG’s encoder in the opj_dwt_calc_explicit_stepsizes() function. This flaw allows an attacker who can supply crafted input to decomposition levels to cause a buffer overflow. The highest threat from this vulnerability is to system availability.

CVSS: 8.8EPSS: 11%CPEs: 6EXPL: 1CVE-2021-29472 – Missing argument delimiter can lead to code execution via VCS repository URLs or source download URLs on systems with Mercurial in composer
https://notcve.org/view.php?id=CVE-2021-29472
Composer is a dependency manager for PHP. URLs for Mercurial repositories in the root composer.json and package source download URLs are not sanitized correctly. Specifically crafted URL values allow code to be executed in the HgDriver if hg/Mercurial is installed on the system. The impact to Composer users directly is limited as the composer.json file is typically under their own control and source download URLs can only be supplied by third party Composer repositories they explicitly trust to download and execute source code from, e.g. Composer plugins. • https://blog.sonarsource.com/php-supply-chain-attack-on-composer https://getcomposer.org https://github.com/composer/composer/security/advisories/GHSA-h5h8-pc6h-jvvx https://lists.debian.org/debian-lts-announce/2021/05/msg00009.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FAQUAMGO4Q4BLNZ2OH4CXQD7UK4IO2GE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KN3DMFH42BJW45VT6FYF2RXKC26D6VC2 https://www.debian.org/security/2021/dsa-4 • CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') CWE-94: Improper Control of Generation of Code ('Code Injection') •
