Sicherheitslücken: 31
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.
ltdl.c in libltdl in GNU Libtool 1.5.x, and 2.2.6 before 2.2.6b, as used in Ham Radio Control Libraries, Q, and possibly other products, attempts to open a .la file in the current working directory, which allows local users to gain privileges via a Trojan horse file.
Heap-based buffer overflow in the CCITTFaxStream::lookChar method in xpdf/Stream.cc in Xpdf 3.02p11 allows remote attackers to execute arbitrary code via a PDF file that contains a crafted CCITTFaxDecode filter.
Integer overflow in the DCTStream::reset method in xpdf/Stream.cc in Xpdf 3.02p11 allows remote attackers to execute arbitrary code via a crafted PDF file, resulting in a heap-based buffer overflow.
Array index error in the DCTStream::readProgressiveDataUnit method in xpdf/Stream.cc in Xpdf 3.02pl1, as used in poppler, teTeX, KDE, KOffice, CUPS, and other products, allows remote attackers to trigger memory corruption and execute arbitrary code via a crafted PDF file.
Integer overflow in the StreamPredictor::StreamPredictor function in xpdf 3.02, as used in (1) poppler before 0.5.91, (2) gpdf before 2.8.2, (3) kpdf, (4) kdegraphics, (5) CUPS, (6) PDFedit, and other products, might allow remote attackers to execute arbitrary code via a crafted PDF file that triggers a stack-based buffer overflow in the StreamPredictor::getNextLine function.
