Mandriva: Updated libtiff packages fixes tiff2pdf vulnerability Print E-mail
User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Mandrake A buffer overflow in the t2p_write_pdf_string function in tiff2pdf in libtiff 3.8.2 and earlier allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via a TIFF file with a DocumentName tag that contains UTF-8 characters, which triggers the overflow when a character is sign extended to an integer that produces more digits than expected in a sprintf call.

 Problem Description:
 
 A buffer overflow in the t2p_write_pdf_string function in tiff2pdf in
 libtiff 3.8.2 and earlier allows attackers to cause a denial of service
 (crash) and possibly execute arbitrary code via a TIFF file with a
 DocumentName tag that contains UTF-8 characters, which triggers the
 overflow when a character is sign extended to an integer that produces
 more digits than expected in a sprintf call.
 
 Corporate Server 3 and Corporate Desktop 3 are not affected by this 
 vulnerability as tiff2pdf was not part of the libtiff version shipped
 in those products.
 
 The updated packages have been patched to correct this issue.
