How to fix?

Upgrade SLES:16.0.0 php8-sqlite to version 8.4.26-160000.1.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php8-sqlite package and not the php8-sqlite package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

phar_tar_number() parses the octal size field of a TAR header into a uint32_t with no overflow check. The field is 11 octal digits wide and holds values up to 0x1FFFFFFFF, so a size above 0xFFFFFFFF silently wraps. The parser then skips the wrong number of data blocks and interprets attacker-controlled file content as the next TAR header, which lets a crafted archive inject entries that PharData reports and extracts as if they were genuine.
