K13288506: Wget vulnerability CVE-2017-13090

Security Advisory Description The retr.c:fdreadbody function is called when processing OK responses. When the response is sent chunked in wget before 1.19.2, the chunk parser uses strtol to read each chunk's length, but doesn't check that the chunk length is a non-negative number. The code then...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in the validateprotocol function in extensions/autolink.c, which exposes malloc metadata. NOTE: The maintainers believe this is harmless. PoC sh echo "to:[email protected]" | ./src/cmark-gfm -e autolink Remediation...
