Descriptions

An issue was discovered in OpenEXR before 2.5.2. An invalid tiled input file could cause invalid memory access in TiledInputFile::TiledInputFile() in IlmImf/ImfTiledInputFile.cpp, as demonstrated by a NULL pointer dereference.

Se detectó un problema en OpenEXR versiones anteriores a v2.5.2. Un archivo de entrada de mosaico no válido podría provocar un acceso de la memoria no válido en la función TiledInputFile::TiledInputFile() en el archivo IlmImf/ImfTiledInputFile.cpp, como es demostrado por una desreferencia del puntero NULL

An update that fixes three vulnerabilities is now available. This update for openexr fixes the following issues. Fixed a NULL pointer dereference in TiledInputFile:TiledInputFile. Fixed a use-after-free in DeepScanLineInputFile:DeepScanLineInputFile. Fixed a heap buffer overflow in getChunkOffsetTableSize. This update was imported from the SUSE:SLE-15:Update update project.
