Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
smb/client: fix out-of-bounds read in symlink_data()<br />
<br />
Since smb2_check_message() returns success without length validation for<br />
the symlink error response, in symlink_data() it is possible for<br />
iov->iov_len to be smaller than sizeof(struct smb2_err_rsp). If the buffer<br />
only contains the base SMB2 header (64 bytes), accessing<br />
err->ErrorContextCount (at offset 66) or err->ByteCount later in<br />
symlink_data() will cause an out-of-bounds read.
