GLSA-200607-03 : libTIFF: Multiple buffer overflows
High Nessus Plugin ID 22010
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200607-03 (libTIFF: Multiple buffer overflows)
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.
SolutionAll libTIFF users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/tiff-3.8.2-r1'
