Descripción técnica

A flaw was found in libarchive. An attacker can cause a Denial of Service (DoS) or potential information disclosure due to a use-after-free vulnerability, which occurs when a program reads memory that has already been released. This issue arises when the archive_entry_copy_mac_metadata() function deallocates an internal buffer before completing a data copy. An attacker who can supply input to an application utilizing this function can trigger the flaw to crash the application or read uninitialized memory data.

———Text::CSV_XS versions from 1.46 before 1.65 for Perl have a use-after-free of bind_columns variables when skip_empty_rows skips an empty line in getline. With bind_columns, the parser writes each field into the caller's own scalar without taking a reference to it. When skip_empty_rows skips an empty last line, the parser frees the current field scalar without checking whether it is bound, dropping one reference from the application's variable. The "eof" mode does the same on any empty line. The variable is then freed while the application still references it, so later code uses freed memory and can crash the process.7h CVE-2026-857489.9 CRÍ

——0MariaDB server is a community developed fork of MySQL server. From 12.3.1 until 12.3.3 and 13.0.2, SYS_REFCURSOR handling is affected because cursor-array reallocation can leave stale references in routine contexts. A low-privileged attacker can open a large number of SYS_REFCURSORs and then fetch one to trigger a use-after-free that can enable remote code execution when combined with another vulnerability. This issue is fixed in versions 12.3.3 and 13.0.2.12h CVE-2026-1109228.8 ALT
