Description:
Two vulnerabilities have been reported in the Linux Kernel, which can be exploited by malicious people to potentially compromise a user's system.
1) A boundary error in the processing of tag 11 packets can be exploited to cause a stack-based buffer overflow via an eCryptfs file containing a specially crafted metadata section.
2) A boundary error in the "parse_tag_3_packet()" eCryptfs function can be exploited to cause a heap-based buffer overflow via a tag 3 packet containing an overly large encrypted key size.
Successful exploitation may allow execution of arbitrary code, but requires that a user is tricked into processing a specially crafted eCryptfs file.
The vulnerabilities are reported in version 2.6.30.3. Other versions may also be affected.
