Text::CSV_XS versions before 1.62 for Perl have a use-after-free when registered callbacks extend the Perl argument stack, which may enable type confusion or memory corruption. The Parse, print, getline, and getline_all methods invoke registered callbacks (for example after_parse, before_print, or on_error) and cache the Perl argument stack pointer across the call. If a callback extends the argument stack enough to trigger a reallocation, the return value is written through the stale pointer into the freed buffer, and the caller reads the original $self argument as the return value instead. Calling code that expects parsed data from getline_all receives the Text::CSV_XS object in its place, leading to logic errors or crashes. Text::CSV_XS objects used without any registered callbacks are not affected.

The remote Debian 11 / 12 host has a package installed that is affected by a vulnerability as referenced in the dla-4648 advisory.

    A use-after-free issue was found in libtext-csv-xs-perl, a Perl C/XS     module to process Comma-Separated Value files, which may yield type     confusion or memory corruption when registered callbacks extend the Perl     argument stack.

    For Debian 11 bullseye, this problem has been fixed in version     1.45-1+deb11u1.

    For Debian 12 bookworm, this problem has been fixed in version     1.49-1+deb12u1.

    We recommend that you upgrade your libtext-csv-xs-perl packages.
