Title: Adobe Reader: User-assisted execution of arbitrary code (GLSA 200901-09)
Date: January 13, 2009
Adobe Reader is vulnerable to execution of arbitrary code.
Adobe Reader (formerly Adobe Acrobat Reader) is a closed-source PDF reader.
Vulnerable: < 8.1.3
Unaffected: >= 8.1.3
Architectures: All supported architectures
- An unspecified vulnerability can be triggered by a malformed PDF document, as demonstrated by 2008-HI2.pdf (CVE-2008-2549).
- Greg MacManus of iDefense Labs reported an array index error that can be leveraged for an out-of-bounds write, related to parsing of Type 1 fonts (CVE-2008-4812).
- Javier Vicente Vallejo and Peter Vregdenhil, via Zero Day Initiative, reported multiple unspecified memory corruption vulnerabilities (CVE-2008-4813).
- Josh Bressers of Red Hat reported an untrusted search path vulnerability (CVE-2008-4815).
- Peter Vreugdenhil reported through iDefense that the Download Manager can trigger a heap corruption via calls to the AcroJS function (CVE-2008-4817).
A remote attacker could entice a user to open a specially crafted PDF document, and local attackers could entice a user to run acroread from an untrusted working directory. Both might result in the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.
There is no known workaround at this time.
All Adobe Reader users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/acroread-8.1.3"
