Created ghostscript tracking bugs for this issue: Affects: fedora-all [bug 1870268] Flaw summary: In routine pj_common_print_page() of file /devices/gdevpjet.c, the `data` buffer was uninitialized. Later in the routine, that data was being used to index a global buffer, which could lead to a out-of-bounds read of various size, depending on the uninitialized data. The patch 0-initializes the `data` buffer using memset() to prevent this. Mitigation: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability. This issue has been addressed in the following products: Red Hat Enterprise Linux 8 Via RHSA-2021:1852 https://access.redhat.com/errata/RHSA-2021:1852 This bug is now closed. Further updates for individual products will be reflected on the CVE page(s): https://access.redhat.com/security/cve/cve-2020-16288 |
