GNU libextractor before 1.16 loads plugins from an untrusted search path specified by the LIBEXTRACTOR_PREFIX environment variable without proper privilege checks. A local attacker can exploit this by setting LIBEXTRACTOR_PREFIX to a directory containing a malicious plugin that executes arbitrary code with elevated privileges when loaded by a setuid or setgid program.
GNU libextractor before 1.15 contains a stack-based buffer overflow vulnerability in the process_star_office function that sizes a variable-length stack array from attacker-controlled OLE2 stream data. Attackers can craft malicious StarOffice documents that allocate up to 4 MB on the stack, causing stack overflow and crashing any application extracting metadata from the document.
GNU Libextractor through 1.9 has a heap-based buffer over-read in the function EXTRACTOR_dvi_extract_method in plugins/dvi_extractor.c.
GNU Libextractor through 1.8 has a NULL Pointer Dereference vulnerability in the function process_metadata() in plugins/ole2_extractor.c.
GNU Libextractor through 1.8 has an out-of-bounds read vulnerability in the function history_extract() in plugins/ole2_extractor.c, related to EXTRACTOR_common_convert_to_utf8 in common/convert.c.
GNU Libextractor through 1.7 has an out-of-bounds read vulnerability in EXTRACTOR_zip_extract_method() in zip_extractor.c.
GNU Libextractor before 1.7 contains an infinite loop vulnerability in EXTRACTOR_mpeg_extract_method (mpeg_extractor.c).
GNU Libextractor before 1.7 has a stack-based buffer overflow in ec_read_file_func (unzip.c).
GNU Libextractor 1.6 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted GIF, IT (Impulse Tracker), NSFE, S3M (Scream Tracker 3), SID, or XM (eXtended Module) file, as demonstrated by the EXTRACTOR_xm_extract_method function in plugins/xm_extractor.c.
In GNU Libextractor 1.4, there is an out-of-bounds read in the EXTRACTOR_dvi_extract_method function in plugins/dvi_extractor.c.
In GNU Libextractor 1.4, there is an integer signedness error for the chunk size in the EXTRACTOR_nsfe_extract_method function in plugins/nsfe_extractor.c, leading to an infinite loop for a crafted size.
In GNU Libextractor 1.4, there is a heap-based buffer overflow in the EXTRACTOR_png_extract_method function in plugins/png_extractor.c, related to processiTXt and stndup.
In GNU Libextractor 1.4, there is a NULL Pointer Dereference in the EXTRACTOR_nsf_extract_method function of plugins/nsf_extractor.c.
In GNU Libextractor 1.4, there is a NULL Pointer Dereference in flac_metadata in flac_extractor.c.
In GNU Libextractor 1.4, there is a Divide-By-Zero in EXTRACTOR_wav_extract_method in wav_extractor.c via a zero sample rate.
