CVE-2015-2313
HighSummary
In Sandstorm Cap'n Proto versions before 0.4.1.1 and 0.5.x before 0.5.1.2, the totalSize method on an object reader can be exploited by remote peers to cause a denial of service through a crafted small message, leading to high CPU consumption.
Risk Assessment
The organization may face significant performance issues, potentially resulting in service availability interruptions.
Recommendation
It is recommended to upgrade to the latest version of Sandstorm Cap'n Proto to mitigate this vulnerability and other known issues.

An integer underflow in Sandstorm Cap'n Proto before version 0.4.1.1 and 0.5.x before 0.5.1.1 may allow remote peers to cause a denial of service or potentially obtain sensitive information from memory or execute arbitrary code via a crafted message.
- CVE-2015-2310Critical
Integer overflow in layout.c++ in Sandstorm Cap'n Proto before version 0.4.1.1 and 0.5.x before version 0.5.1.1 allows remote peers to cause a denial of service or possibly obtain sensitive information from memory via a crafted message, related to pointer validation.
Original NVD description (English source)
Sandstorm Cap'n Proto before 0.4.1.1 and 0.5.x before 0.5.1.2, when an application invokes the totalSize method on an object reader, allows remote peers to cause a denial of service (CPU consumption) via a crafted small message, which triggers a "tight" for loop. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-2312.
