AFFLIB multiple buffer overflow

afflib-multiple-bo (33961) The risk level is classified as HighHigh Risk

Description:

AFFLIB and applications using the affected library are vulnerable to multiple stack-based buffer overflows, caused by improper bounds checking by the aimage/aimage.cpp, lib/vnode_afd.cpp, lib/vnode_ewf.cpp, lib/vnode_s3.cpp, and lib/s3.cpp files. By exploiting this vulnerability, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.

  • CVE-2007-2053: Multiple stack-based buffer overflows in AFFLIB before 2.2.6 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via (1) a long LastModified value in an S3 XML response in lib/s3.cpp; (2) a long (a) path or (b) bucket in an S3 URL in lib/vnode_s3.cpp; or (3) a long (c) EFW, (d) AFD, or (c) aimage file path. NOTE: the aimage vector (3c) has since been recalled from the researcher's original advisory, since the code is not called in any version of AFFLIB.
