GLSA 200904-08: OpenSSL: Denial of Service
| Severity: | normal |
| Title: | OpenSSL: Denial of Service |
| Date: | 04/07/2009 |
| Bugs: | |
| ID: | 200904-08 |
Synopsis
An error in OpenSSL might allow for a Denial of Service when printing certificate details.Background
OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general purpose cryptography library.
Affected packages
| Package | Vulnerable | Unaffected | Architecture(s) |
|---|---|---|---|
| dev-libs/openssl | < 0.9.8k | >= 0.9.8k | All supported architectures |
Description
The ASN1_STRING_print_ex() function does not properly check the provided length of a BMPString or UniversalString, leading to an invalid memory access.
Impact
A remote attacker could entice a user or automated system to print a specially crafted certificate, possibly leading to a Denial of Service.
Workaround
There is no known workaround at this time.
Resolution
All OpenSSL users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8k"
