WinRAR / UnRAR RAR5 recovery-volume (.rev) out-of-bounds heap write in RecVolumes5::ReadHeader

An out-of-bounds heap write exists in the RAR5 recovery-volume (.rev) parser in WinRAR and UnRAR (RecVolumes5::ReadHeader in recvol5.cpp). The RecItems vector is sized only when the first .rev file in a set is processed; subsequent .rev files supply an independent RecNum value that is validated against that file's own TotalCount field but never against the actual size of RecItems. A crafted set of two or more .rev files can therefore write an attacker-controlled 32-bit value (the header's RevCRC field) to RecItems[RecNum] at an attacker-controlled offset up to 65534 * sizeof(RecVolItem) bytes past the allocation, corrupting adjacent heap obje

RARLAB WinRAR Recovery Volume Improper Validation of Array Index Remote Code Execution Vulnerability

RARLAB WinRAR Recovery Volume Improper Validation of Array Index Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of RARLAB WinRAR. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the processing of recovery volumes. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the cur

• Update to 1:6.2.6-1+deb12u1

CVE-2024-33899

RARLAB WinRAR before 7.00, on Linux and UNIX platforms, allows attackers to spoof the screen output, or cause a denial of service, via ANSI escape sequences.

CVE-2022-48579

UnRAR before 6.2.3 allows extraction of files outside of the destination folder via symlink chains.

• Update to 1:6.2.3-1

CVE-2022-30333

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. NOTE: WinRAR and Android RAR are unaffected.

• Update to 1:6.1.7-1

CVE-2017-20006

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).

• Update to 1:5.6.6-1

CVE-2018-25018

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.

• Update to 1:5.6.6-1

CVE-2017-12942

libunrar.a in UnRAR before 5.5.7 has a buffer overflow in the Unpack::LongLZ function.

• Update to 1:5.5.8-1

CVE-2017-12941

libunrar.a in UnRAR before 5.5.7 has an out-of-bounds read in the Unpack::Unpack20 function.

• Update to 1:5.5.8-1

CVE-2017-12940

libunrar.a in UnRAR before 5.5.7 has an out-of-bounds read in the EncodeFileName::Decode call within the Archive::ReadHeader15 function.

• Update to 1:5.5.8-1

CVE-2017-12938

UnRAR before 5.5.7 allows remote attackers to bypass a directory-traversal protection mechanism via vectors involving a symlink to the . directory, a symlink to the .. directory, and a regular file.

• Update to 1:5.5.8-1

CVE-2012-6706

A 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. An integer overflow can be caused in DataSize+CurChannel. The result is a negative value of the "DestPos" variable, which allows the attacker to write out of bounds when setting Mem[DestPos].

• Update to 1:5.5.5-1

CVE-2007-3726

Integer signedness error in the SET_VALUE function in rarvm.cpp in unrar 3.70 beta 3, as used in products including WinRAR and RAR for OS X, allows user-assisted remote attackers to cause a denial of service (crash) via a crafted RAR archive that causes a negative signed number to be cast to a large unsigned number.

• Update to 3.7.3-1.1

CVE-2007-0855

Stack-based buffer overflow in RARLabs Unrar, as packaged in WinRAR and possibly other products, allows user-assisted remote attackers to execute arbitrary code via a crafted, password-protected archive.

• Update to 1:3.7.3-1
