Detailsinfo

A vulnerability was found in Linux Kernel up to 2.6.38.8 (Operating System). It has been classified as critical. This affects the function rose_parse_national. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Array index error in the rose_parse_national function in net/rose/rose_subr.c in the Linux kernel before 2.6.39 allows remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact by composing FAC_NATIONAL_DIGIS data that specifies a large number of digipeaters, and then sending this data to a ROSE socket.

The issue has been introduced in 03/14/2011. The weakness was released 06/21/2012 by Dan Rosenberg (Website). It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2011-1493 since 03/21/2011. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit. The pricing for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 12/05/2021).

The vulnerability was handled as a non-public zero-day exploit for at least 465 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 68426 (Oracle Linux 5 / 6 : Unbreakable Enterprise kernel (ELSA-2011-2038)), which helps to determine the existence of the flaw in a target environment.
