{"id":"MGASA-2018-0109","summary":"Updated libtiff packages fix security vulnerability","details":"tools/pal2rgb.c in pal2rgb in LibTIFF 4.0.9 allows remote attackers to\ncause a denial of service (TIFFSetupStrips heap-based buffer overflow and\napplication crash) or possibly have unspecified other impact via a crafted\nTIFF file. (CVE-2017-17095)\n\nIn LibTIFF 4.0.8, there is a heap-based buffer overflow in the t2p_write_pdf\nfunction in tools/tiff2pdf.c. This heap overflow could lead to different\ndamages. For example, a crafted TIFF document can lead to an out-of-bounds\nread in TIFFCleanup, an invalid free in TIFFClose or t2p_free, memory\ncorruption in t2p_readwrite_pdf_image, or a double free in t2p_free. Given\nthese possibilities, it probably could cause arbitrary code execution.\n(CVE-2017-9935)\n\nIn LibTIFF 4.0.9, there is a Null-Pointer Dereference in the tif_print.c\nTIFFPrintDirectory function, as demonstrated by a tiffinfo crash.\n(CVE-2017-18013)\n","modified":"2026-02-02T10:56:59.230330Z","published":"2018-02-06T06:25:44Z","related":["CVE-2017-17095","CVE-2017-18013","CVE-2017-9935"],"references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2018-0109.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=22120"},{"type":"REPORT","url":"http://openwall.com/lists/oss-security/2017/12/02/1"},{"type":"REPORT","url":"https://lists.opensuse.org/opensuse-updates/2018-01/msg00041.html"},{"type":"REPORT","url":"https://www.debian.org/security/2018/dsa-4100"}],"affected":[{"package":{"name":"libtiff","ecosystem":"Mageia:5","purl":"pkg:rpm/mageia/libtiff?arch=source&distro=mageia-5"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.0.9-1.1.mga5"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2018-0109.json"}},{"package":{"name":"libtiff","ecosystem":"Mageia:6","purl":"pkg:rpm/mageia/libtiff?arch=source&distro=mageia-6"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.0.9-1.1.mga6"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2018-0109.json"}}],"schema_version":"1.7.3","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
