The unpatched flaw allows remote attackers to compromise users' computer systems, according to vulnerability tracking firm Secunia.
The vulnerability, discovered by researcher Scott Laurie and posted on Secunia's website, is "due to a boundary error when handling BMP files. This can be exploited to cause a buffer overflow via a BMP file having a malformed header."
It has also been reported, the advisory says, that the vulnerability can be exploited when a storage device, such as a USB drive or camera, is attached to a vulnerable computer.
While the vulnerability is reported in Adobe Photoshop Album Starter Edition 3.2 and Adobe After Effects CS3, other versions of these programs may also be affected.
Adobe Systems confirmed to SCMagazineUS.com today that a security vulnerability has been discovered with Photoshop Album Starter Edition, whereby a malformed bitmap file (.BMP) could cause malicious code to run on a user's machine.
"We are currently investigating this. In the meantime, we suggest steering clear of files in these formats created by unknown/untrusted parties. Because these formats are uncommonly used in Photoshop Album Starter Edition, we don't anticipate this will be a large issue. However, we...will be working on a fix. Stay tuned for more from us on this."
Secunia echoes this suggestion, advising that users of these programs, as they await a patch, donot process untrusted BMP files using the affected applications. Secunia also suggests that users do not connect untrusted storagedevices to the local computer.
As for After Effects, Adobe Systems says it is currently investigating the claim.
