CVE-2018-10779 – libtiff: heap-based buffer over-read in TIFFWriteScanline function in tif_write.c
https://notcve.org/view.php?id=CVE-2018-10779
TIFFWriteScanline in tif_write.c in LibTIFF 3.8.2 has a heap-based buffer over-read, as demonstrated by bmp2tiff. TIFFWriteScanline en tif_write.c en LibTIFF 3.8.2 tiene una sobrelectura de búfer basada en memoria dinámica (heap), tal y como queda demostrado con bmp2tiff. An integer overflow has been discovered in libtiff in TIFFSetupStrips:tif_write.c, which could lead to a heap-based buffer overflow in TIFFWriteScanline:tif_write.c. An attacker may use this vulnerability to corrupt memory or cause Denial of Service. • http://bugzilla.maptools.org/show_bug.cgi?id=2788 http://www.securityfocus.com/bid/104089 https://access.redhat.com/errata/RHSA-2019:2053 https://usn.ubuntu.com/3906-1 https://usn.ubuntu.com/3906-2 https://access.redhat.com/security/cve/CVE-2018-10779 https://bugzilla.redhat.com/show_bug.cgi?id=1577311 • CWE-122: Heap-based Buffer Overflow CWE-125: Out-of-bounds Read •

CVE-2018-7456 – libtiff: NULL pointer dereference in tif_print.c:TIFFPrintDirectory() causes a denial of service
https://notcve.org/view.php?id=CVE-2018-7456
A NULL Pointer Dereference occurs in the function TIFFPrintDirectory in tif_print.c in LibTIFF 3.9.3, 3.9.4, 3.9.5, 3.9.6, 3.9.7, 4.0.0alpha4, 4.0.0alpha5, 4.0.0alpha6, 4.0.0beta7, 4.0.0, 4.0.1, 4.0.2, 4.0.3, 4.0.4, 4.0.4beta, 4.0.5, 4.0.6, 4.0.7, 4.0.8 and 4.0.9 when using the tiffinfo tool to print crafted TIFF information, a different vulnerability than CVE-2017-18013. (This affects an earlier part of the TIFFPrintDirectory function that was not addressed by the CVE-2017-18013 patch.) Una desreferencia de puntero NULL ocurre en la función TIFFPrintDirectory en tif_print.c en LibTIFF versiones 3.9.3, 3.9.4, 3.9.5, 3.9.6, 3.9.7, 4.0.0alpha4, 4.0.0alpha5, 4.0.0alpha6, 4.0.0beta7, 4.0.0, 4.0.1, 4.0.2, 4.0.3, 4.0.4, 4.0.4beta, 4.0.5, 4.0.6, 4.0.7, 4.0.8 Y 4.0.9 al emplear la herramienta tiffinfo para imprimir la información TIFF manipulada.

CVE-2018-5784
https://notcve.org/view.php?id=CVE-2018-5784
In LibTIFF 4.0.9, there is an uncontrolled resource consumption in the TIFFSetDirectory function of tif_dir.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted tif file. This occurs because the declared number of directory entries is not validated against the actual number of directory entries. En LibTIFF 4.0.9, hay un consumo no controlado de recursos en la función TIFFSetDirectory de tif_dir.c. Los atacantes remotos pueden aprovechar esta vulnerabilidad para provocar una denegación de servicio (DoS) mediante un archivo tif manipulado. • http://bugzilla.maptools.org/show_bug.cgi?id=2772 https://gitlab.com/libtiff/libtiff/commit/473851d211cf8805a161820337ca74cc9615d6ef https://lists.debian.org/debian-lts-announce/2018/05/msg00022.html https://lists.debian.org/debian-lts-announce/2018/07/msg00002.html https://usn.ubuntu.com/3602-1 https://usn.ubuntu.com/3606-1 https://www.debian.org/security/2018/dsa-4349 • CWE-400: Uncontrolled Resource Consumption •
