The result is a negative value of the "DestPos" variable, which allows the attacker to write out of bounds when setting Mem. An integer overflow can be caused in DataSize+CurChannel. are unpacked into the upper directory.Ī VMSF_DELTA memory corruption was discovered in unrar before 5.5.5, as used in Sophos Anti-Virus Threat Detection Engine before 3.37.2 and other products, that can lead to arbitrary code execution.

Unrar 0.0.1 (aka unrar-free or unrar-gpl) suffers from a directory traversal vulnerability for RAR v2 archives: pathnames of the form. Unrar 0.0.1 (aka unrar-free or unrar-gpl) suffers from a stack-based buffer over-read in unrarlib.c, related to ExtrFile and stricomp. UnRAR 5.6.1.2 and 5.6.1.3 has a heap-based buffer overflow in Unpack::CopyString (called from Unpack::Unpack5 and CmdExtract::ExtractCurrentFile). UnRAR 5.6.1.7 through 5.7.4 and 6.0.3 has an out-of-bounds write during a memcpy in QuickOpen::ReadRaw when called from QuickOpen::ReadNext. NOTE: this may be the same as one of the several test cases in the CVE-2017-11189 references. The DecodeNumber function in unrarlib.c in unrar 0.0.1 (aka unrar-free or unrar-gpl) suffers from a NULL pointer dereference flaw triggered by a crafted RAR archive. NOTE: WinRAR and Android RAR are unaffected. RARLAB UnRAR before 6.12 on Linux and UNIX allows directory traversal to write to files during an extract (aka unpack) operation, as demonstrated by creating a ~/.ssh/authorized_keys file.
