The XML parser used in ConeXware PowerArchiver before 20.10.02 allows processing of external entities, which might lead to exfiltration of local files over the network (via an XXE attack).

The Encrypt Files feature in ConeXware PowerArchiver before 14.02.05 uses legacy ZIP encryption even if the AES 256-bit selection is chosen, which makes it easier for context-dependent attackers to obtain sensitive information via a known-plaintext attack.

Heap-based buffer overflow in ConeXware PowerArchiver before 10.20.21 might allow remote attackers to execute arbitrary code via a long filename in a BlackHole archive.

Multiple stack-based buffer overflows in the (1) LoadTree and (2) ReadHeader functions in PAISO.DLL 1.7.3.0 (1.7.3 beta) in ConeXware PowerArchiver 2006 9.64.02 allow user-assisted attackers to execute arbitrary code via a crafted ISO file containing a file within several nested directories.

Stack-based buffer overflow in DZIPS32.DLL 6.0.0.4 in ConeXware PowerArchiver 9.62.03 allows user-assisted attackers to execute arbitrary code by adding a new file to a crafted ZIP archive that already contains a file with a long name.

Multiple stack-based buffer overflows in PowerArchiver 8.10 through 9.5 Beta 4 and Beta 5 allow remote attackers to execute arbitrary code via a long filename in a (1) ACE or (2) ARJ archive.
