GLSA-200903-26 : TMSNC: Execution of arbitrary code
Critical Nessus Plugin ID 35916
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200903-26 (TMSNC: Execution of arbitrary code)
Nico Golde reported a stack-based buffer overflow when processing a MSN packet with a UBX command containing a large UBX payload length field.
A remote attacker could send a specially crafted message, possibly resulting in the execution of arbitrary code.
There is no known workaround at this time.
SolutionSince TMSNC is no longer maintained, we recommend that users unmerge the vulnerable package and switch to another console-based MSN client such as CenterIM or Pebrot:
# emerge --unmerge 'net-im/tmsnc'
