Transmission: Multiple vulnerabilities

1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
net-p2p/transmission	< 1.92	>= 1.92	All supported architectures

Related bugreports: #309831

Stack-based buffer overflows in Transmission may allow for remote execution of arbitrary code.

2. Impact Information

Transmission is a cross-platform BitTorrent client.

Multiple stack-based buffer overflows in the tr_magnetParse() function in libtransmission/magnet.c have been discovered.

A remote attacker could cause a Denial of Service or possibly execute arbitrary code via a crafted magnet URL with a large number of tr or ws links.

3. Resolution Information

There is no known workaround at this time.

All Transmission users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-p2p/transmission-1.92"
