CVE-2008-2664

HIGH 7.8EPSS 4.28%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (4.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

The rb_str_format function in Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, 1.8.7 before 1.8.7-p22, and 1.9.0 before 1.9.0-2 allows context-dependent attackers to trigger memory corruption via unspecified vectors related to alloca, a different issue than CVE-2008-2662, CVE-2008-2663, and CVE-2008-2725. NOTE: as of 20080624, there has been inconsistent usage of multiple CVE identifiers related to Ruby. The CVE description should be regarded as authoritative, although it is likely to change.
