mozilla -- 64 bit JIT WASM read on left over memory
[email protected] reports: On 64-bit CPUs, when the JIT compiles WASM i32 return values they can pick up bits from left over memory. This can potentially cause them to be treated as a different type.
Affected versions
- firefox < 136.0,2
- firefox-esr < 115.21,1
- librewolf < 136.0
- thunderbird < 136.0
By system
2 still vulnerable, 5 fixed. Where VuXML applies (FreeBSD, DragonFly, FreeBSD's derivatives) a port is vulnerable while its version is in a range; pkgsrc says itself whether it lists a CVE of this advisory; OpenBSD and MidnightBSD keep no list this site reads, so their row is only an estimate: FreeBSD's ranges applied to upstream's version.
