GLSA 200711-10: Mono: Buffer overflow
| Severity: | high |
| Title: | Mono: Buffer overflow |
| Date: | 11/07/2007 |
| Bugs: | |
| ID: | 200711-10 |
Synopsis
Mono's BigInteger implementation contains a buffer overflow vulnerability that might lead to the execution of arbitrary code.Background
Mono provides the necessary software to develop and run .NET client and server applications on various platforms.
Affected packages
| Package | Vulnerable | Unaffected | Architecture(s) |
|---|---|---|---|
| dev-lang/mono | < 1.2.5.1-r1 | >= 1.2.5.1-r1 | All supported architectures |
Description
IOActive discovered an error in the Mono.Math.BigInteger class, in the reduction step of the Montgomery-based Pow methods, that could lead to a buffer overflow.
Impact
A remote attacker could exploit this vulnerability by sending specially crafted data to Mono applications using the BigInteger class, which might lead to the execution of arbitrary code with the privileges of the user running the application (possibly root) or a Denial of Service.
Workaround
There is no known workaround at this time.
Resolution
All Mono users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/mono-1.2.5.1-r1"
