Background ========== libTIFF provides support for reading and manipulating TIFF images. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/tiff < 3.8.2-r1 >= 3.8.2-r1 Description =========== A buffer overflow has been found in the t2p_write_pdf_string function in tiff2pdf, which can been triggered with a TIFF file containing a DocumentName tag with UTF-8 characters. An additional buffer overflow has been found in the handling of the parameters in tiffsplit. Impact ====== A remote attacker could entice a user to load a specially crafted TIFF file, resulting in the possible execution of arbitrary code. Workaround ========== There is no known workaround at this time.
