Mandrake Linux Security Advisory : libtiff (MDKSA-2006:102)
High Nessus Plugin ID 21717
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionA 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.
SolutionUpdate the affected packages.
