libTIFF contains buffer overflows that could result in arbitrary code execution.
|Package||media-libs/tiff on all architectures|
|Affected versions||< 3.8.2-r1|
|Unaffected versions||>= 3.8.2-r1|
libTIFF provides support for reading and manipulating TIFF images.
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.
A remote attacker could entice a user to load a specially crafted TIFF file, resulting in the possible execution of arbitrary code.
There is no known workaround at this time.
All libTIFF users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/tiff-3.8.2-r1"
