Vulnerability Assessment Details

[GLSA-200702-12] CHMlib: User-assisted remote execution of arbitrary code

Vulnerability Assessment Summary
CHMlib: User-assisted remote execution of arbitrary code

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200702-12
(CHMlib: User-assisted remote execution of arbitrary code)


When certain CHM files that contain tables and objects stored in pages
are parsed by CHMlib, an unsanitized value is passed to the alloca()
function resulting in a shift of the stack pointer to arbitrary memory
locations.

Impact

A possible hacker could entice a user to open a specially crafted CHM file,
resulting in the execution of arbitrary code with the permissions of
the user viewing the file.

Workaround

There is no known workaround at this time.
