Vulnerabilidades

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…

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…

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.

Multiple heap-based buffer overflows in Libextractor 0.5.13 and earlier allow remote attackers to execute arbitrary code via (1) the asf_read_header function in the ASF plugin (plugins/asfextractor.c), and (2) the parse_trak_atom function in the QT plugin (plugins/qtextractor.c).

Unspecified vulnerability in certain versions of xpdf after 3.00, as used in various products including (a) pdfkit.framework, (b) gpdf, (c) pdftohtml, and (d) libextractor, has unknown impact and user-assisted attack vectors, possibly involving errors in (1) gmem.c, (2) SplashXPathScanner.cc, (3) JBIG2Stream.cc, (4)…

Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (crash) via a crafted FlateDecode stream that triggers a null dereference.

Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (infinite loop) via streams that end prematurely, as demonstrated using the (1) CCITTFaxDecode and (2) DCTDecode streams, aka "Infinite CPU spins."

The CCITTFaxStream::CCITTFaxStream function in Stream.cc for xpdf, gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others allows attackers to corrupt the heap via negative or large integers in a CCITTFaxDecode stream, which lead to integer overflows and integer underflows.
