Debian Security Advisories

DSA-3778 ruby-archive-tar-minitar – security update

Michal Marek discovered that ruby-archive-tar-minitar, a Ruby library
that provides the ability to deal with POSIX tar archive files, is prone
to a directory traversal vulnerability. An attacker can take advantage
of this flaw to overwrite arbitrary files during archive extraction via
a .. (dot dot) in an extracted filename.

DSA-3774 lcms2 – security update

Ibrahim M. El-Sayed discovered an out-of-bounds heap read vulnerability
in the function Type_MLU_Read in lcms2, the Little CMS 2 color
management library, which can be triggered by an image with a specially
crafted ICC profile and leading to a heap memory leak or
denial-of-service for applications using the lcms2 library.

DSA-3772 libxpm – security update

Tobias Stoeckmann discovered that the libXpm library contained two
integer overflow flaws, leading to a heap out-of-bounds write, while
parsing XPM extensions in a file. An attacker can provide a specially
crafted XPM file that, when processed by an application using the libXpm
library, would cause a denial-of-service against the application, or
potentially, the execution of arbitrary code with the privileges of the
user running the application.
