acroread in Adobe Acrobat Reader 4.05 on Linux allows local users to overwrite arbitrary files via a symlink attack on temporary files.

The control for Adobe Reader 5.0.9 and 5.0.10 on Linux, Solaris, HP-UX, and AIX creates temporary files with the permissions as specified in a user's umask, which could allow local users to read PDF documents of that user if the umask allows it.

UNVERIFIABLE NOTE: this issue describes a problem that can not be independently verified as of 20050421. Adobe Acrobat reader (AcroRd32.exe) 6.0 and earlier allows remote attackers to cause a denial of service ("Invalid-ID-Handle-Error" error) and modify memory beginning at a particular address, possibly allowing the execution of arbitrary code, via a crafted PDF file. NOTE: the vendor has stated that the reporter refused to provide sufficient details to confirm the issue. In addition, due to the lack of details in the original advisory, an independent verification is not possible. Finally, the reliability of the original reporter is unknown. This item has only been assigned a CVE identifier for tracking purposes, and to serve as a concrete example of the newly defined UNVERIFIABLE and PRERELEASE content decisions in CVE, which must be discussed by the Editorial Board. Without additional details or independent verification by reliable sources, it is highly likely that this item will be REJECTED.

Adobe Acrobat Reader 6.0.3 and 7.0.0 allows remote attackers to cause a denial of service (application crash) via a PDF file that contains a negative Count value in the root page node.

Adobe Reader and Acrobat 10.x before 10.1.16 and 11.x before 11.0.13, Acrobat and Acrobat Reader DC Classic before 2015.006.30094, and Acrobat and Acrobat Reader DC Continuous before 2015.009.20069 on Windows mishandle junctions in the Synchronizer directory, which allows attackers to delete arbitrary files via Adobe Collaboration Sync, a related issue to CVE-2015-2428.
