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

High Nessus Plugin ID 24732


The remote Gentoo host is missing one or more security-related patches.


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 :

An attacker 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.


All CHMlib users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/chmlib-0.39'
