| Severity: | normal |
| Title: | T1Lib: Buffer overflow |
| Date: | 10/12/2007 |

| ID: | 200710-12 |
Synopsis
T1Lib is vulnerable to a buffer overflow allowing for the user-assisted execution of arbitrary code.Background
T1Lib is a library for rasterizing bitmaps from Adobe Type 1 fonts.
Affected packages
| Package | Vulnerable | Unaffected | Architecture(s) |
|---|---|---|---|
| media-libs/t1lib | < 5.0.2-r1 | >= 5.0.2-r1 | All supported architectures |
Description
Hamid Ebadi discovered a boundary error in the intT1_EnvGetCompletePath() function which can lead to a buffer overflow when processing an overly long filename.
Impact
A remote attacker could entice a user to open a font file with a specially crafted filename, possibly leading to the execution of arbitrary code with the privileges of the user running the application using T1Lib.
Workaround
There is no known workaround at this time.
Resolution
All T1Lib users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/t1lib-5.0.2-r1"
