Descripción:	Summary: The remote host is missing an update for the 'libXcursor' package(s) announced via the SSA:2017-333-01 advisory. Vulnerability Insight: New libXcursor packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1, 14.2, and -current to fix a security issue. Here are the details from the Slackware 14.2 ChangeLog: +--------------------------+ patches/packages/libXcursor-1.1.15-i586-1_slack14.2.txz: Upgraded. Fix heap overflows when parsing malicious files. (CVE-2017-16612) It is possible to trigger heap overflows due to an integer overflow while parsing images and a signedness issue while parsing comments. The integer overflow occurs because the chosen limit 0x10000 for dimensions is too large for 32 bit systems, because each pixel takes 4 bytes. Properly chosen values allow an overflow which in turn will lead to less allocated memory than needed for subsequent reads. The signedness bug is triggered by reading the length of a comment as unsigned int, but casting it to int when calling the function XcursorCommentCreate. Turning length into a negative value allows the check against XCURSOR_COMMENT_MAX_LEN to pass, and the following addition of sizeof (XcursorComment) + 1 makes it possible to allocate less memory than needed for subsequent reads.
