Name of the Vulnerable Software and Affected Versions yasm version 1.3.0.55.g101bc

Description A stack overflow issue was discovered in yasm via the parse expr1 function at /nasm/nasm-parse.c. This issue has been disputed by third parties, who argue it is a bug rather than a security issue due to yasm being a standalone program not designed to run untrusted code.

Recommendations For yasm version 1.3.0.55.g101bc, as a temporary workaround, consider disabling the parse expr1 function until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
