Severity ?
8.8 (High) - CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
CWE
  • CWE-121 - Stack-based Buffer Overflow
Summary
The http.c:skip_short_body() function is called in some circumstances, such as when processing redirects. When the response is sent chunked in wget before 1.19.2, the chunk parser uses strtol() to read each chunk's length, but doesn't check that the chunk length is a non-negative number. The code then tries to skip the chunk in pieces of 512 bytes by using the MIN() macro, but ends up passing the negative chunk length to connect.c:fd_read(). As fd_read() takes an int argument, the high 32 bits of the chunk length are discarded, leaving fd_read() with a completely attacker controlled length argument.

When the response is sent chunked in wget before 1.19.2, the chunk parser uses strtol() to read each chunk\u0027s length, but doesn\u0027t check that the chunk length is a non-negative number. The code then tries to skip the chunk in pieces of 512 bytes by using the MIN() macro, but ends up passing the negative chunk length to connect.c:fd_read(). As fd_read() takes an int argument, the high 32 bits of the chunk length are discarded, leaving fd_read() with a completely attacker controlled length argument.\"},{\"lang\":\"es\",\"value\":\"Se llama a la funci\u00f3n http.c:skip_short_body() en ciertas circunstancias, como cuando se procesan redirecciones. Cuando la respuesta se env\u00eda fragmentada en wget en versiones anteriores a la 1.19.2, el analizador de fragmentos utiliza srtol() para leer la longitud de cada fragmento, pero no comprueba si esta longitud es un n\u00famero no negativo. El c\u00f3digo entonces intenta saltarse el fragmento en partes de 512 bytes utilizando la macro MIN(), pero acaba pasando la longitud negativa del fragmento a connect.c:fd_read().
