| Severity: | normal |
| Title: | teTeX: Multiple buffer overflows |
| Date: | 09/27/2007 |

| ID: | 200709-17 |
Synopsis
Multiple vulnerabilities have been discovered in teTeX, allowing for user-assisted execution of arbitrary code.Background
teTeX is a complete TeX distribution for editing documents.
Affected packages
| Package | Vulnerable | Unaffected | Architecture(s) |
|---|---|---|---|
| app-text/tetex | < 3.0_p1-r4 | >= 3.0_p1-r4 | All supported architectures |
Description
Mark Richters discovered a buffer overflow in the open_sty() function in file mkind.c. Other vulnerabilities have also been discovered in the same file but might not be exploitable (CVE-2007-0650). Tetex also includes vulnerable code from GD library (GLSA 200708-05), and from Xpdf (CVE-2007-3387).
Impact
A remote attacker could entice a user to process a specially crafted PNG, GIF or PDF file, or to execute "makeindex" on an overly long filename. In both cases, this could lead to the remote execution of arbitrary code with the privileges of the user running the application.
Workaround
There is no known workaround at this time.
Resolution
All teTeX users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/tetex-3.0_p1-r4"
