Descripción
*** Pendiente de traducción *** 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.<br />
<br />
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.<br />
<br />
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.
