Title: LittleCMS: Multiple vulnerabilities (GLSA 200904-19)
Date: April 19, 2009
Bug(s): #260269, #264604
Multiple errors in LittleCMS allow for attacks including the remote execution of arbitrary code.
LittleCMS, or short lcms, is a color management system for working with ICC profiles. It is used by many applications including GIMP and Firefox.
Vulnerable: < 1.18-r1
Unaffected: >= 1.18-r1
Architectures: All supported architectures
RedHat reported a null-pointer dereference flaw while processing monochrome ICC profiles (CVE-2009-0793). Chris Evans of Google discovered the following vulnerabilities:
- LittleCMS contains severe memory leaks (CVE-2009-0581).
- LittleCMS is prone to multiple integer overflows, leading to a heap-based buffer overflow (CVE-2009-0723).
- The ReadSetOfCurves() function is vulnerable to stack-based buffer overflows when called from code paths without a bounds check on channel counts (CVE-2009-0733).
A remote attacker could entice a user or automated system to open a specially crafted file containing a malicious ICC profile, possibly resulting in the execution of arbitrary code with the privileges of the user running the application or memory exhaustion, leading to a Denial of Service condition.
There is no known workaround at this time.
All LittleCMS users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/lcms-1.18-r1"
