Vulnerabilidades de Libyal

libewf through 20260924 contains a heap out-of-bounds read vulnerability in libewf_lef_extended_attribute_read_data() because UTF-16 name and value sizes are validated before being doubled. Attackers can supply a crafted .L01/.Lx01 file with oversized 'ea' metadata counts to crash the application or leak uninitialized heap memory through extended attributes.

Libyal libesedb through 20260704 contains a heap out-of-bounds read vulnerability in libesedb_record_get_multi_value() that allows attackers to read past buffers via unbounded multi-value offset tables. Attackers can supply a crafted ESE/EDB database processed by esedbexport to crash the application or expose up to about 32 KiB of adjacent heap memory.

libregf through 20260526 contains a heap out-of-bounds read in libregf_value_item_read_value_data() because it bounds value data size without subtracting the 4-byte old-format cell offset. Attackers can supply a crafted version 1.0/1.1 REGF hive with a value data cell ending its hive bin to leak adjacent heap bytes or crash parsers like regfexport and plaso.

libfwsi through 20260522 contains a heap out-of-bounds read vulnerability in libfwsi_mtp_volume_values_read_data() that allows attackers to read past buffer bounds via crafted MTP volume shell items. Attackers can embed a 10 to 53 byte shell item with item data size of 44 or more in a .lnk file, jump list or shell bag to crash consuming processes.

libfwsi through 20260522 contains a heap out-of-bounds read vulnerability in libfwsi_mtp_file_entry_values_read_data() that allows attackers to read past buffer bounds via crafted MTP file entry shell items. Attackers can embed a 10 to 73 byte shell item with item data size of 44 or more in .lnk files, jump lists or shell bags to crash libfwsi consumers.

libfsapfs through 20260921 contains an integer underflow in libfsapfs_key_encrypted_key_read_data() that allows attackers to trigger heap out-of-bounds reads via crafted KEK attributes. Attackers can supply a crafted encrypted APFS image with malformed HMAC or wrapped KEK attribute lengths to crash fsapfsinfo, pyfsapfs, dfVFS or plaso and read adjacent heap memory before password checks.

Libyal libpff through 20260926 contains an integer underflow in libpff_record_entry_get_multi_value() that allows attackers to trigger heap out-of-bounds reads via non-monotonic multi-value offsets. Attackers can craft PST, OST or PAB files with decreasing PT_MV_STRING8, PT_MV_UNICODE or PT_MV_BINARY offsets to crash libpff, pypff or pffexport and expose adjacent heap memory.
