- (NASM: Buffer overflow vulnerability)
-
-
- Jonathan Rockway discovered that NASM-0.98.38 has an unprotected
- vsprintf() to an array in preproc.c. This code vulnerability may lead
- to a buffer overflow and potential execution of arbitrary code.
-
- Impact
-
- A remote attacker could craft a malicious object file which, when
- supplied in NASM, would result in the execution of arbitrary code with
- the rights of the user running NASM.
-
- Workaround
-
- There is no known workaround at this time.

- # emerge --sync
- # emerge --ask --oneshot --verbose ">=dev-lang/nasm-0.98.38-r1"
